Update icudt46l.dat and related files.

Update icudt46l.dat and related files.

We're about to enable using icudt46l.dat instead of static-linking it on
Linux, Android and Chrome OS.

While testing that CL, it's found that source/data/in/icudt46l.dat was not
updated last time when {linux,mac,android}/icudt*S and windows/icudt.dll
were updated.

The following two items are also updated:

1) The timezone data (latest version : 2013h)
2) Added trnslit/{tr,el,az}_{Upper,Lower,Title}.txt and
translit/css3transform.txt so that we can support CSS3 locale-dependent
transform.

With the above changes, all the ICU data files (*.S, *dll, *dat) on
all platforms are regenerated.

The section on the ICU data file generation in README.chromium was made
clearer as to where to find / how to generate *S and *dat files if one
wishes to customize ICU data differently than Chromium does.

BUG=72633, 292214, 234797, 304911
TEST=Once ICU is rolled in, 1) build goes fine 2) Israeli DST transition is up to date (see bug 292214 comment 9 as to how to test).

Mark, can you take a look? 

This CL is mostly date update. I decided to update ICU 46 data one last time
before going to ICU 51.2.

Three  assembly files (*.S for Linux/Mac/Android) are not uploaded because the
patches are too large, but  will be landed with this CL.

LGTM. In the description, do you want 292214 in the BUG list? You duped 310987
into that.

Committed patchset #4 manually as r239289 (presubmit successful).

File source/data/translit/css3transform.txt (right):

https://codereview.chromium.org/102283003/diff/30001/source/data/translit/css...
source/data/translit/css3transform.txt:7: // File: root.txt
Where did this file come from? I can't find it in the ICU trunk or in release
52-1. Was it hand-generated? Can we fix up the "root.txt" comment as well? Sorry
for the posthumous question...
