This WIP PR adds a generic
sycl::halfclass that is supported on all backends/compilation flows, however, when native half support is unavailable, arithmetic operations may be carried out in fp32.This PR only provides the class itself and basic arithmetic functionality, no math builtins. Also no tests yet :P
Depends on #862, because implementing this requires taking into account the SSCP future.
