MSVC doesn't support generating __vectorcall calls in Arm64EC mode, but it does treat it as a distinct type. The Microsoft STL depends on this functionality. (Not sure if this is intentional.) Add support for parsing the same way as MSVC, and add some checks to ensure we don't try to actually generate code. The error handling in CodeGen is ugly, but I can't think of a better way to do it.
