ANDROID: add file for recording allowed ABI breaks

The tooling is configured to block any changes that has a chance to
break ABI, including the possibly safe:

* replacement of ANDROID_KABI_RESERVE with ANDROID_KABI_USE
* changes to internal structures that are not accessible to modules
* addition of enumerators

These changes are difficult for the tooling to identify as definitively
non-breaking, therefore, a human reviewer must check the change and
approve it as non-breaking.

This change adds a file to record the approval with the change that was
marked as breaking. This allows the tooling to:

* unblock presubmits for the change
* don't block presubmits when it is cherry-picked to another branch
* filter compatibility reports between a release branch and a tip of the
  development branch it was forked from

The file is prefilled with all breaks that happened from the KMI freeze.
