new packages: shotcut, mlt and their deps

[knyipab]

Draft PR. currently the app mostly works well but cannot output video results, perhaps there are problems with QProcess, see #20354 . [fixed]

Other things to note:

• [fixed] 32-bit arch does not build (see error log, related to qint64 type)
• [fixed] GPU mode requires PR new package: movit #20352 , related to [Help] Cross compile movit (shotcut & mlt GPU deps), which can build on-device #20351
• [optional] rtaudio (mlt optional deps) needs ALSA and jack API, we may need a functioning pipewire, related to [Bug]: pipewire seems not tested and it is not working #20316
• [optional: someone may try] opencv cannot be included as mltbuild deps (which is done by Archlinux), prompting some compilation error related to QPrivate when building shotcut

This package will be ready and I will force-push it once #20352 and #20374 are merged.
The sound effects should work with sdl2 package. jack-dummy is more for runtime purpose (won't produce sound) otherwise need to patch the code. rtaudio is a longer run TODO item when pipewire is in a good state. opencv is nice-to-have item if someone find a fix but that shouldn't matter much.

Please make sure to add

termux_step_pre_configure(){
	CXXFLAGS+=' -Wno-c++11-narrowing'
}

to make sure the 32 bit builds succeed.

Thanks and will do when movit is available

[TomJo2000]

In that case I'm gonna go ahead and merge movit.

Tested on my aarch64 phone. Import playlist, track editor, preview, some basic filters (rotate, opacity), export work.

Ready to be merged. See if you are fine with the way I patch the source code.

Please change all the .patch files that hardcoded with /data/data/com.termux/files/usr to @TERMUX_PREFIX@

[knyipab]

fixed. thanks

x11-packages/mlt/0001-cmake-mlt-undefined-version.patch and x11-packages/mlt/0002-cmake-mlt++-undefined-version.patch are probably not required. The issue can be fixed with LDFLAGS+=" -Wl,--undefined-version" (see packages/zlib/build.sh).

[knyipab]

Thanks @Biswa96 . You are right and force-pushed.

[truboxl]

Please change TERMUX_PKG_MAINTAINER field

[knyipab]

oh right, fixed.

@truboxl refactored: addressed your comments, used the jack merged in #20544, removed TODO, and removed the libjack.so.0 patch.
