This CL reverts the changes to use the top level namer in the various backends. This is causing issues when rolling into Dawn in the case where the tint generator is used to create SPIR-V which is sent to SPIRV-Cross but then generator and inspector aren't used. The entry points end up being incorrect as SPIRV-Cross gets the renamed entry points.
