Add support for BSWAP intrinsic (#18398)
With this change, the JIT will recognize a call to BinaryPrimitives.ReverseEndianness and will emit a bswap instruction.
This logic is currently only hooked up for x86 and x64; ARM still uses fallback logic.
If the JIT can't emit a bswap instruction (for example, trying to emit a 64-bit bswap in a 32-bit process), it will fall back to a software implementation, so the APIs will work across all architectures.
