[ARM,MVE] Remove 64-bit variants of vbrsrq* intrinsics

[miyuki]

Summary

According to the ACLE the vbrsrq* intrinsics don't accept vectors
with 64-bit elements (and neither does the corresponding VBRSR
instruction).

... and we weren't testing the accidental 64-bit builtins (or else we'd have spotted the problem!), so no tests need to be changed. LGTM.
