[SYCL][CUDA] Ignore cuda prefetch hint if not supported (#5043)

Specific devices and OS's, like Windows, do not support concurrent managed memory. cudaPrefetchAsync requires concurrent managed access for unified memory. This PR removes the windows error message and replaces it with a check for concurrent managed access. As the SYCL prefetch operation is a hint, this can return a success.

Let me know if there is a preferred error code to throw. Also, if it is best that a user warning is printed to indicate that the hint is being ignored as the device does not support the operation.

[SYCL] Make local accessor argument allocation 1-byte minimum (#6032)

Some DPC++ backends, such as OpenCL, does not allow setting local memory
kernel arguments with a size of zero bytes. As such, the runtime library
can fail with a backend error if a local accessor has a zero-size. These
changes make a special case for local accessors with a zero byte size
making it allocate a single byte of memory.

[SYCL][libclc][CUDA] Add --ffast-math support (#5801)

This patch allows the `--ffast-math` compiler
flag to substitute the regular `genfloatf` math
built-ins with their `::native` versions.

Moreover, this patch completes the support of natives
built-ins for `libclc/ptx-nvidiacl` connecting
them with the `__nv_fast` functions present in
libdevice. If a fast function is not available in
libdevice the corresponding `nvvm` intrinsic is used.
