Copy ICU4C 55 RC from icu-project.org to aosp/icu55.

These files were exported from the ICU Subversion repository by running
the following command:

svn export \
  http://source.icu-project.org/repos/icu/icu/tags/release-55-rc/ icu4c

Only the subdirectory "source" and the files in the root directory were
added in this commit. The other subdirectories only contain files that
are not relevant (as_is, packaging) when using ICU4C in Android.
