The registers used to passed arguments to the DxeCore entrypoint in the inline

This change replaces the inline assembly by a pure assembly source file to
avoid this kind of optimization.
Note: Inline assembly is generally not recommanded in system programming.

Fixed issues with X64 clang, and also make StackSwitch push a zero on the new stack to prevent a stack unwind into memory that is no longer valid.

Make MSFT tool chain uses the ASM version, which can handle the case in an size efficient way.
