ACPICA: Implement simplified Table Manager

Browse Source 
The Table Manager component has been completely
redesigned and reimplemented. The new design is much
simpler, and reduces the overall code and data size of
the kernel-resident ACPICA by approximately 5%. Also,
it is now possible to obtain the ACPI tables very early
during kernel initialization, even before dynamic memory
management is initialized.
