aspects that come from references to types in the
`sycl_types_that_use_aspects` list.

* If a function has the `!sycl_declared_aspects` metadata, creates (or augments)
the function's `!sycl_used_aspects` metadata with aspects from the
`!sycl_declared_aspects` list.

* Propagates each function's `!sycl_used_aspects` metadata up the static call
graph so that each function lists the aspects used by that function and by
any functions it calls.
