To enable AARCH64 native instruction support for Openssl,

Add ArmReadCntPctReg() to read system count.
A similar ArmReadCntPct() function is available in the ArmPkg,
but the CryptoPkg where OPENSSL_rdtsc will reside cannot rely
on the ArmPkg.
This is patently untrue, as can be discovered by grepping for ArmPkg
under CryptoPkg already.
Yes right, I will update the serie in that sens,

Yes, we have a problematic history around how architectures that
weren't already in tree when edk2 was first published got
introduced at a later date. But this bit of contortionism helps no one.
Please move this to ArmPkg, which is effectively an exclave of MdePkg
anyway.
(Yes, there is an argument for moving ArmLib into MdePkg, but that
quickly escalates through dependencies to moving all of ArmPkg into
MdePkg, and that's a fairly big task.)
