Integration of release 13 into official QuestZDoom

[emawind84]

This pull request contains all the updates for the release 13

Some changes on my part regarding the build are the following: ndkVersion=21.4.7075529 has been specified into build.gradle, since is recommended instead of let the compiler guess the right one.

ndkBuild {
    ...
    if (project.hasProperty("openxr_hmd"))
        arguments 'OPENXR_HMD=' + project.getProperty("openxr_hmd")
}

I added this property openxr_hmd in order to build for meta or pico from the github workflow but I guess it will change with your next update.

Most of the other commits is just me trying to make the github workflow works after the openxr integration.

Once the latest openxr changes are in, I can resolve all the conflicts and it should be possible to merge this PR without any problems.

Merged and fixed

I excluded the local.properties file from git since it should only be created locally and not included with the source code. I also specified the ndkVersion into the gradle.build file, this help to build the project without Android Studio, an example is github workflow. I changed the NDK version to the latest v21 21.4.7075529 you can download the NDK from the SDK Manager in Android Studio. If this create you some problems we can always specify your NDK version instead.

I found this really nice howto regarding NDK configuration https://github.com/android/ndk-samples/wiki/Configure-NDK-Path#introduction
