i386: Use a fallback XSAVE layout for remote targets

If a target provides a target description including registers from the
XSAVE extended region, but does not provide an XSAVE layout, use a
fallback XSAVE layout based on the included registers.  This fallback
layout matches GDB's behavior in earlier releases which assumes the
layout from Intel CPUs.

This fallback layout is currently only used for remote targets since
native targets which support XSAVE provide an explicit layout derived
from CPUID.
