devel/electron25: fix build with libc++ 17
Building www/qt6-webengine with libc++ 17 results in the following
compile errors:
In file included from ../../base/allocator/dispatcher/reentry_guard.cc:9:
In file included from ../../base/debug/crash_logging.h:16:
In file included from ../../base/strings/string_number_conversions.h:15:

../../base/containers/checked_iterators.h:248:8: error: no template named '__is_cpp17_contiguous_iterator'; did you mean '__libcpp_is_contiguous_iterator'?

| ^This is because the copy of chromium in electron25 is missing an
upstream fix for recent libc++ changes, in particular:
https://chromium.googlesource.com/chromium/src/+/9bfbbffdba73668fdb483e5a850911d2b64c35d7
and its dependency:
https://chromium.googlesource.com/chromium/src/+/5b5551edd3961481e617e510276b9f015a35b861
Apply these patches to work around the compile error.
