[llvm] [libc][bazel] Update bazel overlay for ceilf128 emulated float128 changes (PR #216515)

[via llvm-commits]

https://github.com/DeanSturtevant1 created https://github.com/llvm/llvm-project/pull/216515

This updates the Bazel overlay following commit e5174fe683e882f6bbd2ef023c9c9e293b273a98:

- Remove `:llvm_libc_types_float128` from `__support_math_ceilf128` deps as `include/llvm-libc-types/float128.h` is no longer included.
- Add `:__support_cpp_bit` to `ceilf128` additional_deps for `bit_cast`.
- Add `ceilf128` math MPFR test target in `libc/test/src/math/BUILD.bazel`.
