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
   https://chromium.googlesource.com/chromium/deps/icu/+/log/chromium/58staging

  - ar and fa: Prepend 'percent sign' with RTL mark (U+200F). From Android.
  - 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.

The warning complains that StringThreadTest is declared in the global namespace,
but the friend line says `friend class StringThreadTest;` instead of
`friend class ::StringThreadTest`.  MSVC doesn't require this ::, but gcc does
-- without it, the friend line declares a new class in the namespace containing
UnicodeString.

Since StringThreadTest was in test/threadtest which isn't built as part of
Chromium's build and which was removed in upstream ICU in ICU 37392, just
delete the friend line, it has no effect.

Google's locale data changes are applied before Chrome's own locale data
trimming.

1. Use "Rs." instead of the Indian Rupee sign (U+20A8) for which the font
   support is not available on all platforms.
   Google platforms (CrOS / Android ) have them, but other
   platforms may not.
2. Use shorter names for Hong Kong and Macau without 'S.A.R.' at the
   end. This cuts down the data size a bit.
3. Timezone names for Korea standard time and a couple of other zones
   are shortened.
4. zh_Hant_TW, pa_Arab_PK and a few more locales are changed.

Besides, update data.build.patch and README.chromium to drop
the collation rule files ('-R' option to genrb.). This should have been
done in ICU update step 2.

Data size checkpoint: 20,066,624 bytes
 - about 500k reduction from step 3 mostly due to '-R' option with
    the rest attributed to shorter display names for HK, MO and Korean tz.
 - the original ICU 54.1 : 25,343,024

A. Converter update per HTML encoding spec along with changes in
  the encoding name alias table.
B. Remove all the codes for converters Blink and Chromium do not need
(SCSU, Lotus, ISO-2022-xx other than JP, BOCU, UTF-7, etc).

This is reapplying the following CLs (that we used for ICU 52.1) to ICU 54.1 :

https://codereview.chromium.org/598383002
https://codereview.chromium.org/654153002

We have two upstream bugs filed for A and B above:
  http://www.icu-project.org/trac/ticket/11296
  http://www.icu-project.org/trac/ticket/10303

In addiition to A and B, we unified Big5 and Big5-HKSCS per
the encoding spec (bug 277868). That also includes properly supporting
the four 2-character sequences ( see http://crbug.com/277868#c3 ).
big5_gen.sh deviates from the current spec to work around a bug
in the spec. (see https://www.w3.org/Bugs/Public/show_bug.cgi?id=27878)

Moreover, ucmlocal.mk is added to list only encodings we want to support.

Also, tighten the state table for windows-946-2000.ucm that we use
for EUC-KR for now. And, drop 'base' map for windows-{936,949}-2000.ucm.

Finally, add euc-kr-html.ucm along with scripts/euckr_gen.sh, but
it is not yet used pending the resolution of bug 450312.

Update the following patches and apply to the fresh copy of icu 54.1:

  configure.patch
  declspec.patch
  locid.patch
  platform_nacl.patch
  regex.patch
  wpo.patch
  vscomp.patch: two chunks are not necessary any more; upstream has
                them.
  data.build.patch
  data.build_win.patch

Delete the following patches:
  putil.patch: not necessary any more; upstream has it.
  regex2.patch: merged to regex.patch.
  col.patch: not necessary any more; upstream code changed drastically
             and does not have a bug any more.
  clang_win.patch: not necessary any more; upstream has it.
