  [AArch64][SME] Store SME attributes in AArch64FunctionInfo (NFC) (#142362)

The SMEAttrs class is tiny (simply a wrapper around a bitmask).
Constructing SMEAttrs from a llvm::Function is relatively expensive (as
we have to redo the checks for every SME attribute). So let's just
construct the SMEAttrs as part of the AArch64FunctionInfo and reuse the
parsed attributes where possible.
