core: Support fetching x86 XSAVE layout from architectures.
Add gdbarch_core_read_x86_xsave_layout to fetch the x86 XSAVE layout
structure from a core file.
Current OS's do not export the offsets of XSAVE state components in
core dumps, so provide an i387_guess_xsave_layout helper function to
set offsets based on known combinations of XCR0 masks and total state
sizes. Eventually when core dumps do contain this information this
function should only be used as a fall back for older core dumps.
