MdePkg/BaseLib: Add linked list iteration macros

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1959



The macros EFI_LIST_FOR_EACH and EFI_LIST_FOR_EACH_SAFE have been
duplicated across several drivers. These macros have proven useful and
established a commonly used pattern for linked list iteration.

This change defines the macros in BaseLib.h alongside other generic linked
list macros and functions.
