* Under the hood runs Chromium 87.0.4280.144 with security fixes up to
version 96.0.4664.110 and patches were taken from of www/chromium
87.0.4280.141 (391acded85).
* Prune some unneeded patches (mostly from the headless and unittest
areas) and try to align the unbundling of dependencies similar to
qt6-webengine for consistency.
* Adjust Mk/Uses/qt-dist.mk accordingly as the naming of the distfiles
has changed since Qt 5.15.3.
