[AArch64][SME] Disable tail-call optimization when streaming mode change or lazy-save may be required. When a streaming mode change is (or may be) required for a call, it will need to restore the original mode after the call, which prevents the use of tail-call optimization. The same holds true for a call that requires the lazy-save mechanism to be set up before the call, and possibly restored after. More details about the SME attributes and design can be found in D131562. Reviewed By: aemerson Differential Revision: https://reviews.llvm.org/D131579
