REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3246
RFC: https://edk2.groups.io/g/devel/message/72530


Patch 1 is to add RegisterFilterLib Library Class in edk2 to filter/trace port IO/MMIO/MSR access and add a RegisterFilterLibNull instance.
Last 2 patches are to update APIs in IoLib and BaseLib to filter/trace port IO/MMIO/MSR access.
Remaining patches are to update related dsc files to consume RegisterFilterLibNull instance.

Will submit patch 1 firstly and then update related dsc files in edk2 and edk2platform repo to consume RegisterFilterLibNull instance.
At last will submit the patches to update IoLib and BaseLib to filter/trace port IO/MMIO/MSR access.
