    drm/xe: Introduce Xe assert macros
    
    As we are moving away from the controversial XE_BUG_ON macro,
    relying just on WARN_ON or drm_err does not cover the cases
    where we want to annotate functions with additional detailed
    debug checks to assert that all prerequisites are satisfied,
    without paying footprint or performance penalty on non-debug
    builds, where all misuses introduced during code integration
    were already fixed.
    
    Introduce family of Xe assert macros that try to follow classic
    assert() utility and can be compiled out on non-debug builds.
    
    Macros are based on drm_WARN, but unlikely to origin, disallow
    use in expressions since we will compile that code out.
    
    As we are operating on the xe pointers, we can print additional
    information about the device, like tile or GT identifier, that
    is not available from generic WARN report:
