  -----------
  [Clang] Introduce `nonblocking`/`nonallocating` attributes (#84983)

Introduce `nonblocking` and `nonallocating` attributes. RFC is here:
https://discourse.llvm.org/t/rfc-nolock-and-noalloc-attributes/76837

This PR introduces the attributes, with some changes in Sema to deal
with them as extensions to function (proto)types.

There are some basic type checks, most importantly, a warning when
trying to spoof the attribute (implicitly convert a function without the
attribute to one that has it).

A second, follow-on pull request will introduce new caller/callee
verification.
