ICU header move part 3 of 3.
Delete public directory. It's landed manually because 'gcl upload' does
not work when deleting empty directories.
All-in-one CL was reviewed and approved at
https://codereview.chromium.org/18836004/
The upstream has headers in source/{common,i18n}/unicode.
With Blink's ICU headers removed, there's no need to keep them
in a location different than the upstream. Future ICU updates will
be a bit more streamlined. v8 also likes to have this change.
The Chrome-side of change is at http://codereview.chromium.org/18252003
This revision will be rolled in along with the global replacements
of include-references to ICU headers and DEPS changes.
See also http://crbug.com/232922 where ICU headers in Blink are removed.
