Fix precompiledTargetModule tests (#6455)

* Fix precompiledTargetModule tests

Add SPIRV-Tool linker support to gfx unit tests
and use the linker in precompileModule tests
that use precompiled modules to reconstitute
SPIRV shaders that were modularly compiled.

Fix a Slang reference count bug in the
precompile service.

* Use sm_6_6

New DXC requires higher version
for linkability.

* Rename helper function, pass by reference

* Link through slang-glslang

* Add missing files

* Fix metal

* format code
