Note: Doesn't do APK generation, to keep things simple, instead using
the old NDK build.
Later should run gradle on github CI too, I guess.
Fixes#15981
There are some deprecations coming and some actions might stop working.
It seems softprops/action-gh-release@v1 is not being actively maintained,
and isn't updated here.
the mac os build action uses an action that automatically creates
a release from a tag push, which circumvents triggering the regular
release actions.
also switch from the unmaintained actions/upload-release-asset@v1
to the active softprops/action-gh-release@v1 action.
closes#15761
whenever a release is created on github using "make new release",
CI will automatically create a tarball containing all sources
including submodules and upload it.
this makes it much easier for distros to build ppsspp using their
existing workflow, without having to resort to running git from
build scripts.
