ArmPkg/ArmMmuLib: Drop buggy secure memory type check
Jake reports that the IS_ARM_MEMORY_REGION_ATTRIBUTES_SECURE() macro is
no longer accurate since commit 852227a9d52e3cb9 ("ArmPkg/Mmu: Remove
handling of NONSECURE memory regions").
Fortunately, it only affects the NS bit in level 1 short descriptors,
which is ignored when executing in non-secure mode. And given that
running UEFI in the secure world is not a use case we aim to support,
let's just drop this logic altogether.
