Subject: Support status argument for GatherXXX (#4490)

* Support status argument for GatherXXX

This commit adds an argument to all texture GatherXXX functions.
The new argument is for "status" as described in SM5.0 definision.

Close #4466

Limit Gather with status to HLSL

Exclude Gather-status test from VK

* Fix capability errors
