www/qt5-webengine: Update to 5.13.0

Under the hood runs Chromium 73.0.3683.105 with applied security fixes from
Chrome up to version 74.0.3729.157.

Most of the patches were synced with www/chromium 73.0.3683.103 (= r498089)
with some re-added/modified patches from r497877 and r499210 to get also
successful builds on aarch64. Some tweaking might still be needed to get
positive build results on the armv7 architecture.

Other notable changes:

* GN keywords "use_system_{libusb,libcxx}" aren't used anymore thus both
  were removed from the FreeBSD specific qmake file "freebsd.pri".

* In various GN files the OS is now identified as "freebsd" (prior it was
  "bsd") so "mkspecs/features/functions.prf" was changed accordingly.

* The hook up of the sandbox feature is no longer excluded which led to some
  more patches (= patch-*crashpad* files)

* Add "xorg" to USES as using USE_XORG alone is deprecated.
