[AArch64][SME] Rewrite __arm_get_current_vg to preserve required registers (#100143)
The documentation for the __arm_get_current_vg support routine specifies
that the following registers are call-preserved:
 - X1-X15, X19-X29 and SP
 - Z0-Z31
 - P0-P15

This patch rewrites the implementation of this routine in compiler-rt,
as the current version does not guarantee that these registers will be
preserved.
