feature: enable xe drm detection by default

driver is built with xe drm support by default

added cmake flag to control xe eu debug API support
NEO_ENABLE_XE_EU_DEBUG_SUPPORT

This flag is disabled by default and uapi-eu-debug headers are not
needed for driver compilation as these headers are not a part of
upstream kernel yet.
