Add logging for binary transparency atoms.

Browse Source 
Added logging for vbmeta digest after devices boots.

Added logging for APEX Info after their SHA256 digests
are computed.

Bug: 214300670
Test: Build compiles and `statsd_testdrive` shows that
the atoms are recorded correctly and as expected.
