virgl: add shader offset alignment to to v2 caps struct
This is the SSBO analogue to fe0647. User supplied data must be a multiple of GL_SHADER_STORAGE_BUFFER_OFFSET_ALIGNMENT. This fixes 44 GLES31 tests on airlied@'s GLES31 sketch branches with Nvidia hardware, but this patch standalone can applied to master. The alignment restriction on Nvidia is 32, hence the default value. Example tests: dEQP-GLES31.functional.ssbo.layout.random.all_shared_buffer.0 dEQP-GLES31.functional.ssbo.layout.multi_basic_types.single_buffer.std430 v2: Move to a better place in case statement v3: Rebase Reviewed-by: Dave Airlie <[email protected]>
