Recent changes in detecting big endian targets don't work when cross

this.

Follw-up to https://chromium.googlesource.com/chromium/deps/icu/+/5feb9ad5
(due to a rietveld issue, part 1 was manually pushed).

Update ICU to 58.1 release from ICU 56.1 part2.

Listed below a tiny subset of what's new in 58.1:

  1. Unicode 9.0 from Unicode 8.0
    - Updated character properties including Emoji data up to 4.0beta.
    - Updated grapheme/word/line breaking rules for Emoji sequences and others.

  2. CLDR 30.0.2 from CLDR 28
    - Numerous locale data updates/improvements

  3. Spoofing API changes
  4. Greek uppercasing support as a part of regular case-mapping API.
  5. Line breaking rule file format optimization. This change enables me
     to add CJ loose line breaking rules back (previously, it's dropped
     to save space) so that Blink can use it for CJ.

See http://site.icu-project.org/download/58 for more details on ICU 58.1
and http://site.icu-project.org/download/57 for more details on ICU 57.1

For CLDR 30, see http://cldr.unicode.org/index/downloads/cldr-30 .

The size impact:
   Non-Android: 10,127,200 => 10,128,624 (delta = 1,424 / 0.014%)
   Android: 6,563,152 => 6,571,936 (delta = 8,784 / 0.13%)

Below are the list of changes made on top of the upstream ICU 58.1
in reverse order. Most of these changes were made in 58staging branch
to run trybots and cherry-picked back for this CL. See

  - tr: Use ₺ (U+20BA; Turkish Lira Sign) instead of 'TL'. This is to revert a locale patch picked up from Google's internal build of ICU. (Android also uses U+20BA).

In addition, icudtl.dat (the prebuilt ICU data file for platforms other than
Android is moved out of source/data/in to common/. This way, the data build
steps for non-Android and Android can be unified and a bit more streamlined.

1. Update ucmlocal.mk and convertrs.txt to refer to euc-kr-html.ucm
instead of windows-949.ucm

2. Tighten up the valid code range for the following converters:

   EUC-KR, Shift_JIS, Big5

This is to add back an ASCII range byte to the stream per
the encoding spec when they're either illegal as a 'trail byte' or
there's no assigned code point for a "lead + trail" sequence.
For instance, with this change, '0xF3 0x41' in EUC-KR is converted to
'U+FFFD U+0041' instead of 'U+FFFD'.

This change requires adding 2 ~ 8 new states to the conversion
table of each converter mentioned above leading to 6.5kB net increase
in the final data size.

3. Tighten the trail byte range for 2-byte sequences starting with 0x8E
from [A1,E2] to [A1,DF] in EUC-JP and update the corresponding generating
script.

4. Change the substitution characters for EUC-JP and Shift_JIS to
match other converters. i.e. make them produce U+FFFD when encountering
an invalid input. Before this chaange, they emitted U+001A.

5. Enable 'U_CHARSET_IS_UTF8' configuration flag.
Chromium/Blink does not rely on ICU for the code conversion between
the 'system native encoding' (if it's one of legacy encodings)
and Unicode. With this configuration, we can cut down the code size
a bit.

6. Update the icudtl.dat (all platforms) and assembly files (mac,linux)
   and the icudata dll (windows)

UCONFIG_NO_NON_HTML5_CONVERTER was added earlier to our copy of ICU, but
it was never set to 1.  It's my oversight.

1. Turns UCON..CONVERTER on in icu.gyp to drop all the encodings not
   required by the Encoding spec. Dropped encodings include
   UTF-7, BOCU, SCSU, CESU, ISCII, ISO-2022-{KR, CN*}, HZ-GB, ISO-2022-JP's
   other than the original.

2. A lot more sections of the ICU converter code are excluded when
   it's set to 1 including the code for LMB (Lotus Multibyte) encodings and
   X11 compound text encoding (icu common).

3. The character encoding detections for encodings excluded are also disabled.
   (icu i18n)

4. ISO-2022-{KR, CN*} and HZ-GB can be dropped now because Blink treats them
   as replacement encoding. The corresponding alias entries from convertrs.txt
   are also removed.

5. ibm-874 was removed. We used to need it before Blink started, but not any
   more. We only need windows-874.

6. A mistaken in convertrs.txt was corrected : Big5-HKSCS was pointing to
   an old mapping table.

7. Per ICU upstream's suggestion, use '-html' suffix instead of '-html5'
for the encoding tables derived from the WHATWG's encoding spec (ibm866,
shift_jis and euc-jp).

The static 64-bit release build of Chrome on Linux went down from
141,596,616 to 141,491,968 bytes (~ 100 kB reduction). Besides, the icu data
size got smaller by ~ 19 kB ( 10,490,576 to 10,471,008 bytes).

ICU fails to gyp when run with GYP_DEFINES="android_webview_build=1
use_system_icu=0 use_system_stlport=1" which is a combination of
settings we're trying to bring up temporarily as we migrate away from
system libraries. It fails because it's not permitted to specify
link_settings in a target_condition as the processing is too late.

Remove the invalid link_settings, since we can't do this outside
target_conditions as it's not valid to use -lgabi++ on the host build of
ICU. The link dependency on gabi++ will have to be satisfied manually in
the main libwebviewchromium target instead for this configuration.

dl_open and friends are only used by ICU plugins that we don't use.
Nacl-related targets (with newlib) fail because dlfcn.h is missing.

Setting U_ENABLE_DYLOAD to 0, we don't have to worry about dlfcn.h any more (it's not included)

BUG=132145
TEST=After running build/gyp_chromium, build 'base_i18n_nacl' target. It should succeed without complaining about dlfcn.h.

Add a shell script to trim the ICU data further : trim_data.sh along with
locale list files.  The script does the following:

1. Remove the display names of languages NOT listed in Chrome's Accept-Language
   list. (800kB)
2. Minimize the locale data for locales listed in the A-L list that are
   not a UI locale in Chrome. For those locales, exemplar characters,
   the display name in the native language and layout direction are included.
   (640kB)
3. Filter the region data to drop numeric region display names other than 419
   (Latin-America). (50kB)
4. Filter the currency data (display name and plurals) for historic currencies.
   (200kB)

This CL also checks in icudtl.dat (source/data/in) and
icudt_dat.S (mac and linux). Note that I dropped '52' (the version number)
in the assembly source file name and icu.gyp was adjusted accordingly.

With all these changes, icudtl.dat is ~ 800kB larger than that in ICU 4.6.
The 7z compression (as used by the installer) makes the size difference
go down to ~ 130kB.

BUG=132145
TEST=The icudtl.dat (uncompressed) is about 10.7MB instead of 12.4MB without this CL.

Update icu.gyp and related files to list C/C++ source files and header files.

Besides, HAVE_DLOPEN is set to 0 explicitly in icu.gyp. It's 0 by default
in ICU 4.6.1 but is 1 by default in ICU 52.1, but we don't need it. (it's only
necessary for ICU plugins that Chromium does not use).

I also applied https://codereview.chromium.org/218153002/ (Nico's CL to
simplify icu.gyp).

BUG=132145
TEST=None
