  [clang][SYCL] Implement address space attributes for SYCL (#200849)

This PR adds SYCL address space attributes. These attributes are
intended for use in the implementation of SYCL run-time libraries and
should not be used in any other context.

The following attributes were added - [[clang::sycl_private]],
[[clang::sycl_global]], [[clang::sycl_local]], [[clang::sycl_constant]]
and [[clang::sycl_generic]]. These correspond to the five address spaces
described by SYCL 2020 section 3.8.2, "SYCL device memory model" and
SYCL 2020 section 4.7.7, "Address space classes".
