Update Android build setup

[SaschaWillems]

Description

The Android build setup for our samples is heavily outdated, making it impossible to locally build them with recent Android build tools (e.g. Android Studio) unless you find a way to manually download and setup the exact versions of the build related tools we require,

This makes it nigh impossible to easily build our samples on Android.

This PR fully updates our Android build scripts and setups to support up-to-date Android build tools, including the current version of Android Studio ("Ladybug"). So people wanting to build on Android can simply download Android studio, generate the project files and then easily build the samples.

It also fixes a few issue with our build files that only showed up with more recent build tools. One such change is a deprecation in the native bridge from C++ to Android, which required a fix in the framework (otherwise it would no longer compile).

Note that this is a fairly pervasive change. I did multiple builds, both release and debug from a clean setup to make sure this properly works. I also had to update some third party dependencies to make everything compile with updated compiler toolchains used on Android. I also updated the Android validation layers to the most recent release.

This hopefully fixes all the reported issues people had with trying to build our samples on Android.

General Checklist:

Please ensure the following points are checked:

• My code follows the coding style
• I have reviewed file licenses
• I have commented any added functions (in line with Doxygen)
• I have commented any code that could be hard to understand
• My changes do not add any new compiler warnings
• My changes do not add any new validation layer errors or warnings
• I have used existing framework/helper functions where possible
• My changes do not add any regressions
• I have tested every sample to ensure everything runs correctly
• This PR describes the scope and expected impact of the changes I am making

Note: The Samples CI runs a number of checks including:

• I have updated the header Copyright to reflect the current year (CI build will fail if Copyright is out of date)
• My changes build on Windows, Linux, macOS and Android. Otherwise I have documented any exceptions

If this PR contains framework changes:

• [] I did a full batch run using the batch command line argument to make sure all samples still work properly
  Note: It does a famework change for Android, but afaik we don't have batch mode on Android. I did test several samples though.
