EFI: Add stubs for multi-threading OSLs to make EFI ported applications running

Browse Source 
This patch only adds stub supports for multi-threading OSLs to make
EFI ported application running.

In order to fully support acpiexec in a non multi-threading environment,
ACPICA core itself need to be upgraded to contain full asynchrnous support.
