Update ICU to 58 part1
* Note that this CL will be followed by CLs with local changes.
Until then, ICU should not be rolled in DEPS. See READ_THIS_FIRST
for details.
* Adjust scripts/update.sh and scripts/data_files_to_preserve.txt
- CLDR/ICU added ckb/ast locale data. Drop them from the list to preserve.
- source/layout does not exist in 58.1 any more.
* Update the tree to ICU 58.1 from the upstream by running
scripts/update.sh
* Update README.chromium and add READ_THIS_FIRST to warn about the
status of the tree.
