ACPICA: Allow to skip Global Lock initialization
Introduce acpi_gbl_use_global_lock, which allows to skip the Global Lock
initialization. This is useful for systems without Global Lock (such as
loong_arch), so as to avoid error messages during boot phase:
ACPI Error: Could not enable global_lock event (20240827/evxfevnt-182)
ACPI Error: No response from Global Lock hardware, disabling lock (20240827/evglock-59)
