drm/xe/tests/pci: Convert GT count check to general device check

We already have check_graphics_ip() and check_media_ip() as general
functions to check the IP descriptors.  The check in
check_platform_gt_count() is simple enough such that we can convert the
function to a more general device check.  In an upcoming change, we will
also add some checks for other members of struct xe_device_desc. As
such, rename check_platform_gt_count() to check_platform_desc().

While at it, use inline (unsigned int) casting of max_gt_per_tile to
keep checks for each member localized; and use KUNIT_EXPECT_*() variants
of the macros to allow multiple issues to be reported.
