[Windows|Arm64|VarArgs] Correctly pass HFA arguments (#18364)
* Fix passing HFA of two floats to vararg methods
Previously, the type would be reported as HFA and enregistered; however,
this is not correct, as arm64 varargs abi requires passing using
int registers.
* Address linux build issue
* Apply final format patch
* Add _TARGET_WINDOWS_
