Trim unit* sections in data/locales/*
Add 'filter_locale_data' function to trim_data.sh
Chromium/Blink do not use most of unit* sections in locale data. Keep
only duration and compound sub-sections.
Update the icudtl.dat and two assembly source files for Mac/Linux.
It saves ~200kB (uncompressed). 7z-compressed size reduction is 34kB.
With all these changes (up to this CL) applied, the net increase of the ICU data from icu 46 to 52 is 49kB with 7z-compressed.
(3,070,246 vs 3,021,457) and ~ 390kB uncompressed (10,370,656 vs 9,980,368 ).
BUG=132145
TEST=None.
