drm/xe: Use Xe assert macros instead of XE_WARN_ON macro

The XE_WARN_ON macro maps to WARN_ON which is not justified
in many cases where only a simple debug check is needed.
Replace the use of the XE_WARN_ON macro with the new xe_assert
macros which relies on drm_*. This takes a struct drm_device
argument, which is one of the main changes in this commit. The
other main change is that the condition is reversed, as with
XE_WARN_ON a message is displayed if the condition is true,
whereas with xe_assert it is if the condition is false.

v2:
- Rebase
- Keep WARN splats in xe_wopcm.c (Matt Roper)

v3:
- Rebase
