Update grammar table generation: - Get extensions from instructions, not just operand-kinds - Don't explicitly list extensions that come from the SPIR-V core grammar or from a KHR extended instruction set grammar. This makes it easier to support new extensions since the recommended extension strategy is to add instructions to the core grammar file. Also, test the validator has trivial support for passing through the extensions SPV_NV_shader_subgroup_partitioned and SPV_EXT_descriptor_indexing.
