CMake: break up glslang into smaller static libs

Add `GenericCodeGen` and `MachineIndependent` static library targets. Privately import both of these into the `glslang` target. Privately import `MachineIndependent` into the `SPIRV` target. This is done to break the dependency of `libglslang.so` non-public APIs from `libspirv.so`, which will become problematic once `glslang` hides its non-public symbols. | File | Before | After | |---------------------------|-----------:|-----------:| | `libGenericCodeGen.a` | - | `527716` | | `libglslang.a` | `68175944` | `512938` | | `libHLSL.a` | `1428` | `1428` | | `libMachineIndependent.a` | - | `67132202` | | `libOGLCompiler.a` | `75908` | `75908` | | `libOSDependent.a` | `23768` | `23768` | | `libSPIRV.a` | `15710210` | `15710210` | | `libSPVRemapper.a` | `3250894` | `3250894` | | File | Before | After | |-----------------------------------------|-----------:|-----------:| | `libglslang-default-resource-limits.so` | `117032` | `117032` | | `libglslang.so` | `22380688` | `22368216` | | `libHLSL.so` | `7520` | `7520` | | `libOGLCompiler.a` | `75908` | `75908` | | `libOSDependent.a` | `23768` | `23768` | | `libSPIRV.so` | `7288336` | `28151016` | | `libSPVRemapper.so` | `1940208` | `1940208` | Issues: #2283, #1484
