  [TargetParser][AArch64] Believe runtime feature detection (#95694)

In https://github.com/llvm/llvm-project/issues/90365 it was reported
that TargetParser arrives at the wrong conclusion regarding what
features are enabled when attempting to detect "native" features on the
Raspberry Pi 4, because it (correctly) detects it as a Cortex-A72, but
LLVM (incorrectly) believes all Cortex-A72s have crypto enabled. Attempt
to help ourselves by allowing runtime information derived from the host
to contradict whatever we believe is "true" about the architecture.
