Define SampleMask as an array

Enables shadow-uncaptured-locals and implicit-fallthrough for Clang.
implicit-fallthrough is not enabled by default in -Wall or -Wextra, and
shadow-uncaptured-local doesn't seem to be enabled by default by
-Wshadow, even though GCC has both of these by their respective cases.

* Depends on the layout dimentions and thus should be recreated as well

* During pipeline configure the function would acquire some payload space from the descriptor update queue,
  write the descriptor data on the GPU thread and give the scheduler a pointer to the beginning of said space to update it later.
  TickFrame resets the payload cursor, used to track acquires, back to the beginning of the buffer.
  This wasn't a problem before since WaitWorker was called at the end of the frame but now it is.
  If a frame writes to a cursor before the scheduler catches up, it will crash

* To fix this the payload buffer has been increased to account for the in flight frames that are allowed to exist now.
  TickFrame will switch between the payload spaces instead of resetting

vk_pipeline_cache: Skip compute pipelines on Intel proprietary drivers

to host.

WIP

Intel's SPIR-V shader compiler is broken. For now, skip compiling any compute pipelines until they fix this issue.
This is not a perfect workaround, as there are a small subset of non-compute pipelines that still cause it to crash, but this should cover the majority of crashes.
It is unfortunate that even with a test case reported 6 months ago the issue has not been fixed in favor of fixing "the most popular games and apps".
Intel, you can do better than this.
