47b490b4 - [AArch64][SME] Refactor MachineSMEABI pass state (NFCI) (#156674)

[AArch64][SME] Refactor MachineSMEABI pass state (NFCI) (#156674) This removes the pass state (aside from target classes) from the MachineSMEABI class, and instead passes/returns state between functions. The intention is to make dataflow (and where state is mutated) more apparent.
