Subject: Move the parse of last_install to recovery-persist

The recovery-persist used to look for the related recovery logs in
persist storage, and copy them under /data/misc/recovery during the
normal boot process.

As we also want to find out the sideload information from last_install,
it makes more sense to move the parse & report of non-a/b metrics to
recovery-persist. Thus we can avoid the race condition of the file
system between the native code and RecoverySystem.

Bug: 114278989
Test: unit test pass, check the event buffer for metrics report
