MdeModulePkg: CoreValidateHandle Optimization
REF : https://bugzilla.tianocore.org/show_bug.cgi?id=4817
Before entering BIOS setup, CoreValidateHandle function executed
over 600,000 times during BDS phase on latest 8S server platform.
In CoreValidateHandle function, current implementation will go
through the doubly-linked list handle database in each call, and
this will have big impact on boot performance.
The optimization is using Red-black tree to store the EFI handle
address when insert each EFI handle into the handle database, and
remove the handle from Red-black tree if the handle is removed
from the handle database. CoreValidateHandle function changed to
go through the Red-black tree.
After verification on latest 8S server platform, BDS boot time can
save 20s+ after this change.
