Subject: This change reflects the Dialer V10 RC00 branch.

RC00 is based on:
branch: dialer-android_release_branch/153304843.1
synced to: 153304843

following the instructions at go/dialer-aosp-release.

In this release:

* Removes final apache sources.
* Uses native lite compilation.

More drops will follow with subsequent release candidates
until we reach our final v10 release, in cadence with our
prebuilt drops.
