Remove deprecated aspects related to atomics, added supported aspects

[oleksandr-pavlyk]

From gh-309 only emulated aspect remains unsupported.

The following aspects from gh-309 are now supported

   sycl::aspect::host_debuggable,
   sycl::aspect::atomic64,
   sycl::aspect::usm_atomic_host_allocations,
   sycl::aspect::usm_atomic_shared_allocations,

Removed (due to deprecation in DPC++) aspects are

    int64_base_atomics
    int64_extended_atomics

• Verified that neither numba-dpex for dpnp make use of removed aspects.

The public CI fails because conda packages still have DPC++ 2022.0.2. These changes require 2022.1.
