[RFC 00/19] Support EU online debug on pagefault

[Gwan-gyeong Mun]

This RFC patch adds a KMD implementation to debug scenarios where
an EU thread causes a pagefault based on GPU Debug support [1].

Fixes code that uses force_wake_[get/put] to work on the latest xe-next,
as the previous version patch[1] does not use
"Fix xe_force_wake_get() failure handling" [2].
