[Sema] Fix crash in __datasizeof with unknown types (#80300 )

Fixes #80284.

Calling `getASTRecordLayout` on invalid types may crash and results of
`__datasizeof` on invalid types can be arbitrary, so just use whatever
`sizeof` returns.

[Clang] Add __datasizeof (#67805 )

The data size is required for implementing the `memmove` optimization
for `std::copy`, `std::move` etc. correctly as well as replacing
`__compressed_pair` with `[[no_unique_address]]` in libc++. Since the
compiler already knows the data size, we can avoid some complexity by
exposing that information.
