Qt 6.8 introduces a new system to manage permissions for websites Building with Qt 6.7 and earlier is unaffected due to extensive preprocessor directives.
The old version of setContent returns bool and takes in pointers to allow access to the error information. This was replaced in Qt 6.5 with a ParseResult struct which allows boolean checking and direct access to the information without additional pointers. The old version had separate overloads to specify whether to use namespace processing or not. This, among other options, can now be specified via ParseOptions which were introduced in Qt 6.5 too.
QDateTime::setTimeSpec is deprecated in Qt 6.9 per documentation, but already emits a warning in Qt 6.8. Anyway, use setTimeZone.

In the upcoming Qt 6.8 release, several deprecations and changes are made. In preparation for that, this PR resolves the emitted warnings when building with Qt 6.8 Beta 3.
Except for the new permissions system introduced in 6.8, the changes modernise the current code and adopt current best practices.
The permissions system changes how Qt handles permission requests from websites. Most importantly, it saves the permissions itself, so we don't have to.
Tested with
permission.site. All new code is enclosed in preprocessor directives, as is the old permission management, to remove it with Qt 6.8+.Builds fine with Qt 6.7.2, Qt 6.8 Beta 3, Qt 5.15.14.
