[SYCL][Graph] Add new 'are_graphs_supported' helper function (#11877)

Add new 'are_graphs_supported' helper function to determine platform
support for Graphs
at runtime rather than the lit '// REQUIRES: <platform>' check at
compile time.

Fixed a bug in the usm_variant tests of trying to instantiate an int
with a float value.

This PR has been create in order to simplify the PR for adding OpenCL
support to the SYCL Graph tests
#11718.
