[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.
