[PATCH i-g-t] tests/intel/xe_query: Sanity check EU width

[Lucas De Marchi]

Add a sanity check for kernel returning the expected EU width in the
topology query.

Signed-off-by: Lucas De Marchi <lucas.demarchi at intel.com>
---

This depends on patch series to be submitted to the kernel. The local
defines are done to be able to test, but should be replaced by an update
to the uapi headers.
