<xutility>: Consider enabling unsized memchr optimization after solving it for ARM64 #2866
Description
DevCom-1615707 is Fixed - Pending Release.
This means we can remove this workaround:
Line 4882 in ef62d3f
This should allow optimizing unsized ranges search when vector algorithms are not enabled. This may be helpful for non-x86.
But the other ARM-specific bug should be taken care of - see https://github.com/microsoft/STL/pull/2434/files#r839094547
