Modules: Rename MemoryBufferCache to InMemoryModuleCache

Change MemoryBufferCache to InMemoryModuleCache, moving it from Basic to
Serialization.  Another patch will start using it to manage module build
more explicitly, but this is split out because it's mostly mechanical.

Because of the move to Serialization we can no longer abuse the
Preprocessor to forward it to the ASTReader.  Besides the rename and
file move, that means Preprocessor::Preprocessor has one fewer parameter
and ASTReader::ASTReader has one more.
