repo init: Added --no-partial-clone and made it persist. Bumped version to 2.14.

Saved the repo.partialclone when --no-partial-clone option is passed
to init, so repo sync will honor the no-partial-clone option.

$ ./run_tests -v

Bug: [google internal] b/175712967

$ mkdir androidx-main && cd androidx-main
$ repo init -u https://android.googlesource.com/platform/manifest -b androidx-main --partial-clone --clone-filter=blob:limit=10M
$ repo sync -c -j32
$ cd frameworks/support/ && /google/bin/releases/android/git_repack/git_unpartial
$ git config -l | grep  'partialclonefilter=blob'

Observe partialclone is not enabled.
