[SYCL] Make builtins accept half pointers (#6596)

Some SYCL math builtins with pointer arguments, such as modf and sincos,
do not currently accept pointers to halfs due to the conversion to
OpenCL types not propagating through pointers. This commit fixes this
by making a special case for pointers, applying the type conversion to
the underlying types.
