psucien 69b305bb40 GnmDriver: Clear context support (#567)
* gnmdriver: added support for gpu context reset

* shader_recompiler: minor validation fixes

* shader_recompiler: added `V_CMPX_GT_I32`

* shader_recompiler: fix for crash on inline sampler access

* compilation warnings and dead code elimination

* amdgpu: fix for registers addressing

* libraries: videoout: reduce logging pressure

* shader_recompiler: fix for devergence scope detection
