[AArch64] SME implementation for agnostic-ZA functions (#120150) This implements the lowering of calls from agnostic-ZA functions to non-agnostic-ZA functions, using the ABI routines `__arm_sme_state_size`, `__arm_sme_save` and `__arm_sme_restore`. This implements the proposal described in the following PRs: * https://github.com/ARM-software/acle/pull/336 * https://github.com/ARM-software/abi-aa/pull/264
