ext: Upgrade PyBind11 to version 2.2.1
This upgrade is necessary for pybind to build with GCC 7.2. We still need to add the patch for stl.h. MSC_FULL_VER change is no longer needed. See https://gem5-review.googlesource.com/c/public/gem5/+/2230 Change-Id: I806729217d022070583994c2dfcaa74476aef30f Signed-off-by: Jason Lowe-Power <jason@lowepower.com> Reviewed-on: https://gem5-review.googlesource.com/5801 Reviewed-by: Andreas Sandberg <andreas.sandberg@arm.com> Maintainer: Andreas Sandberg <andreas.sandberg@arm.com>
