Yanqin Jin cef4a6c49f Compaction filter support for (new) BlobDB (#7974) 
Summary:
Allow applications to implement a custom compaction filter and pass it to BlobDB.

The compaction filter's custom logic can operate on blobs.
To do so, application needs to subclass `CompactionFilter` abstract class and implement `FilterV2()` method.
Optionally, a method called `ShouldFilterBlobByKey()` can be implemented if application's custom logic rely solely
on the key to make a decision without reading the blob, thus saving extra IO. Examples can be found in
db/blob/db_blob_compaction_test.cc.
