  Log Message:
  -----------
  [Support] Integrate SipHash.cpp into libSupport.  (#94394)

Start building it as part of the library, with some minor
tweaks compared to the reference implementation:
- clang-format to match libSupport
- remove tracing support
- add file header
- templatize cROUNDS/dROUNDS, as well as 8B/16B result length
- replace assert with static_assert
- use LLVM_FALLTHROUGH

This also exports interfaces for SipHash-2-4-64/-128, and
tests them using the reference test vectors.
