ACPICA: Executer: Add OSL trace hook support

Browse source 
ACPICA commit e8e4a9b19d0b72a7b165398bdc961fc2f6f502ec

This patch adds OSL trace hook support.

OSPMs are encouraged to use acpi_os_trace_point() with
ACPI_USE_SYSTEM_TRACER defined to implement platform specific trace
facility. Lv Zheng.
