configure: detect & use Qt 6 if present, prefer over Qt 5

Qt 6

`configure` will look for Qt 6 first and only continue looking for Qt
5 if Qt 6 isn't found or disabled via `--disable-qt6`.

Qt 6 detection works by first looking for the `qmake6` binary. Its location
can be specified with the `--with-qmake6=…` option.

All other Qt 6 related facts (such as compiler & linker flags or the
position of the other required tools such as `lconvert`, `moc`, `rcc` and
`uic`) will be derived from the output generated by `qmake6`.

Note that at this point Qt 6 is not yet supported for the cross-compilation
build to Windows, nor is a static Qt 6 build supported yet.

Note that the command line options `--enable-static-qt`,
`--with-qt-pkg-config-modules` and `--without-qt-pkg-config` only apply to
the Qt 5 and have no effect on Qt 6.

Qt 5

The options for specifying the position of the tools (`--with-moc=…`,
`--with-rcc=…` and `--with-uic=…`) have been removed. Their position
will now be derived from the output generated by `qmake`.

General

Completely disabling the GUI now requires passing both `--disable-qt6`
and `--disable-qt` options.

Part of the implementation of #3115.

* mkvmerge, mkvextract: fixed key frame handling for `BlockGroup` elements
with a forward reference but no backward references. Patches by Tom Yan.
## Build system changes
* Qt 6: added support for building with Qt 6. `configure` will look for Qt 6
first and only continue looking for Qt 5 if Qt 6 isn't found or disabled via
`--disable-qt6`.
