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
   https://codereview.chromium.org/2447513002/ : cr+blink update cl with

   to the previous step comes mainly from the compact Khmer dictionary.
 * Android: 17,601,520 bytes. 2MB difference comes from removing cjdict.
