Use static methods `__createFromBinding` and `__createFromImplicitBinding` to initialize individual resources in Sema HLSL instead of calling resource constructor with binding information per proposal update https://github.com/llvm/wg-hlsl/pull/336. Initialization of resources in arrays will be updated in a separate change because that happens in the codegen layer. Test updates include the use of the `llvm-cxxfilt` tool which takes care of demangling of function names for a more readable test baseline.
