MdePkg/BaseLib: Replaced inline assembly for ARMGCC by GCC assembly source file

Browse Source 
The registers used to passed arguments to the DxeCore entrypoint in the inline
assembly function InternalSwitchStackAsm() where switched at compilation time.
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.
