[WIP] kdenlive

[knyipab]

Should bring us closer to a complete KDE. Also prove that qt6-qt5compat #21573 is working.

Some dirty hacks applied on kf6-kconfig to build kdenlive. Help wanted to address such issue, see #21647.

I do not think using separate package for building with cross-compiler is a bad idea. There are a lot of packages like this. You can find a lot of *-cross*.subpackage.sh buildscripts in termux packages. But probably it will be better to move x11-packages/kf6-kconfig-cross/build.sh content to the regular kf6-config build script with moving cross-building stuff to subpackage. This way we will be sure both regular and cross-subpackage have the same version and updated simultaneously.

I agree that it should be in *-cross*.subpackage.sh. Just that kf6 (including kf6-kconfig) uses a lot of extra-cmake-modules syntax and I couldn't figure out a way to make host build cmake to work with that, so I opened #21647. FYI, kf6-kconfig-cross is a dirty hack to build kconfig_compiler_kf6 with pure cmake which I suppose not preferred.

By the way, this Github actions failed and behave differently than that of my branch. My branch is up-to-date and is still building it (https://github.com/knyipab/termux-packages/actions). I expect it to build successfully.

Few things to add:

• forgot to mention that kf6-kconfig-cross requires $TERMUX_PREFIX/include/KF6/KConfig/kconfig_version.h to be available which is generated by cmake cross compilation, so I couldn't find easy way to put it as subpackage.
• [edited] My branch build fails but for different reasons. I will fix that in coming few days. Still, I dunno why this upstream Github Actions behave differently.
• At least my build (https://github.com/knyipab/termux-packages/actions/runs/11171466617) can run on my phone and is able load video.
