[llvm] [bazel][libc] Update MPFR to v4.2.2 (PR #156691)

[Benjamin Barenblat via llvm-commits]

https://github.com/bbarenblat created https://github.com/llvm/llvm-project/pull/156691

Use MPFR v4.2.2 rather than MPFR v4.1.1 for Bazel/Clang builds to avoid conflicts with glibc’s `__float128` fallback typedef. See https://gitlab.inria.fr/mpfr/mpfr/-/commit/c37c9d599b9aced92e182507bf223440bbc9a9f1 for further details.
