spirv/radv: add AMD_gcn_shader capability, remove current extensions
So now, during spirv_to_nir, it uses the capability instead of the extension. Note that we are really doing here is treating SPV_AMD_gcn_shader as other supported extensions. SPV_AMD_gcn_shader is not the first SPV extension supported. For example, the capability draw_parameters infers if the extension SPV_KHR_shader_draw_parameters is supported or not. This could be seen as counter-intuitive, and that it would be easier to define which extensions are supported, and based our checks on that, but we need to take into account that some capabilities are optional from core, and others came from new extensions. Also this commit would make the implementation of ARB_spirv_extensions easier. v2: AMD_gcn_shader capability renamed to gcn_shader (Daniel Schürmann) Reviewed-by: Daniel Schürmann <daniel.schuermann@campus.tu-berlin.de> Reviewed-by: Bas Nieuwenhuizen <bas@basnieuwenhuizen.nl>
