gdbsupport: bump unordered_dense to 4.8.0

We don't need anything in this release, but I think it doesn't hurt to
just stay up to date.  The new version has a new include file, stl.h.
To keep things clean and separated, move the imported files to a new
sub-directory.  This requires a small change in
gdb/check-include-guards.py, to be able to ignore the whole new
directory.
