[clang][Modules] Fix the Size of `RecordDecl`'s `BitCodeAbbrevOp` (#133500)

https://github.com/llvm/llvm-project/pull/102040/files#diff-125f472e690aa3d973bc42aa3c5d580226c5c47661551aca2889f960681aa64dR2477
added 1 bit to `RecordDecl`'s serialization format, but did not
increment its abbreviation size.

This can lead to rare cases where a record may overflow if the
`RecordDecl`'s `getArgPassingRestrictions()` returns something bigger
than 1 (see
[here](https://github.com/llvm/llvm-project/blob/b3f01a6aa45b00240cec1c64286b85d7ba87e2af/clang/lib/Serialization/ASTWriterDecl.cpp#L688)).
