anv: No compression on host memory allocation (xe2)

Browse source 
The Xe kernel driver doesn't allow vm_bind on compressed bo
if it has user pointer. And we probably shouldn't enable CCS
compression on memory in any case.

This change is necessary to prevent failures once we adjust the
priority of compression PAT entries in a following commit:

Vulkan CTS:
dEQP-VK.api.buffer_marker.compute.external_host_mem.top_of_pipe.
memory_dep.buffer_copy

dEQP-VK.memory.external_memory_host.simple_allocation.
minImportedHostPointerAlignment_x3

anv_kmd_backend.c:308: xe_vm_bind_op: Assertion
`errno_ != EINVAL' failed.
