rusticl: experimental support for cl_khr_fp16

Browse Source 
Hidden behind `RUSTICL_ENABLE=fp16` for now as the OpenCL CTS doesn't have
enough fp16 tests at the moment. There has been a lot of work on it though,
so hopefully we can enable and verify it soon.

Additionally libclc also misses a bunch of fp16 functionality, so most of
the tests would also just crash.

However this flag is useful for development as it already wires up most of
the code needed.
