  [AArch64] Add missing TB(N)Z achors to arith+CBZ clustering (#207725)

This patch adds missing TBZ+TBNZ anchors for arith+CBZ clustering. They
have similar nature to CBZ as specific kinds of it, so this patch
classifies them under the same subtarget feature name compactly. This is
better for Apple CPU. They can be reasonably expected to behave
similarly on AArch64 targets.
