  [AArch64][SME2] Extend getRegAllocationHints for ZPRStridedOrContiguousReg (#119865)

ZPR2StridedOrContiguous loads used by a FORM_TRANSPOSED_REG_TUPLE
pseudo should attempt to assign a strided register to avoid unnecessary
copies, even though this may overlap with the list of SVE callee-saved registers.
