[clang] [clang] Fix assertion failure when printing atomic apvalues (PR #85259)

[Timm Baeder via cfe-commits]

https://github.com/tbaederr created https://github.com/llvm/llvm-project/pull/85259

When printing an `_Atomic(some struct type)`, we would later run into an assertion because we do a `Ty->castAs<RecordType>()`, which doesn't work with an `AtomicType`.

Not sure how to best write a test for, this, but OTOH, `printPretty` is currently only  used for debugging as far as I know(?).
