Sync from upstream.

Descriptions:
==========
Switch DocumentStore to using PortableFileBackedProtoLog instead of
FileBackedProtoLog, and migrate any existing FileBackedProtoLog's to the
Portable* version.
==========
Add more fields to SchemaStats to capture the types that were newly
added, modified and modified with an index rebuild.
==========
Create a new DeleteByQueryStatsProto to capture query-specific stats
related to the performance of DeleteByQuery.
==========
Fix bugs in SetSchema:
1. Property id reassignments when a property is deleted and a new one
added was not being detected
2. Property id reassignments due to changes to the
index_nested_properties field were not detected.
3. Backward incompatible changes should invalidate dependent types.
==========
Fix IcingSearchEngineTest.CJKSnippets test by choosing a simpler
multi-byte character (when encoded in UTF-8) string that ICU will always
segment in the same way regardless of api level.
