[clang-format] Fix AllowShortFunctionsOnASingleLine: InlineOnly with wrapping after record.

Fixes https://github.com/llvm/llvm-project/issues/53430.

Initially, I had a quick and dirty approach, but it led to a myriad of special cases handling comments (that may add unwrapped lines).
So I added TT_RecordLBrace type annotations and it seems like a much nicer solution.
I think that in the future it will allow us to clean up some convoluted code that detects records.
