This PR is an incremental improvement regarding semantics I/O in HLSL. This PR allows system semantics to be used on struct type in addition to parameters (state today). This PR doesn't consider implicit indexing increment that happens when placing a semantic on an aggregate/array as implemented system semantics don't allow such use yet. The next step will be to enable user semantics, which will bring the need to properly determine semantic indices depending on context. This PR diverge from the initial wg-hlsl proposal as all diagnostics are done in Sema (initial proposal suggested running diags in codegen). This is not yet a solid semantic implementation, but increases the test coverage and improves the status from where we are now.
