Add an option to override the namespace used for spirv_cross.
This is a pragmatic trick to avoid symbol collision where a project links against SPIRV-Cross statically, while linking to other projects which also use SPIRV-Cross statically. We can end up with very awkward symbol collisions which can resolve themselves silently because SPIRV-Cross is pulled in as necessary. To fix this, we must use different symbols and embed two copies of SPIRV-Cross in this scenario, now with different namespaces, which in turn leads to different symbols.
