Update ICU source from 64.2 to 65.1

Copy the files with the following commands:

1. Obtain ICU sources:

$ cd /tmp
$ git clone --branch release-65-1 --depth 1 https://github.com/unicode-org/icu.git
$ cd icu
$ git lfs pull
$ git lfs ls-files # ensure that all lfs-stored files are checked out

2. Update ICU:

$ find icu4j/ -type f,d ! -regex ".*/\(Android.mk\|Android.bp\|adjust_icudt_path.mk\|liblayout-jarjar-rules.txt\)" -delete
$ find icu4c/ -type f,d ! -regex ".*/\(Android.mk\|Android.bp\)" -delete
$ cp -r /tmp/icu/icu4j/* ./icu4j/
$ cp -r /tmp/icu/icu4c/* ./icu4c/
$ git checkout HEAD -- icu4c/.gitignore icu4j/.gitignore
$ git add -A
