Android port

Fixed compiler errors for Android NDK clang compiler Added drop in replacement for std::jthread for Android NDK clang compiler Added a gradle sub project in the androidplugin directory. This integrates the Java part of the Tilt Five SDK for Android. In TileFiveXRInterface test the Android platform and load the platform context from the Java plugin Handle pause and resume notifications from Android Added Android export in plugin.gd to gather .arr files Enabled Android build in SConstruct Shell out new gradle build in SConstruct Update github CI to assemble zip file with the new Android files. Added Linux build

-This extension requires a C++20 capable compiler.
+This extension requires a C++20 capable compiler. To build for Android you will need Java 17 and the Android SDK along with the r26c NDK.
 
 Things you will need to know how to do.
 * Use [scons](https://scons.org/) 
 * [Build GDExtensions](https://docs.godotengine.org/en/stable/tutorials/scripting/gdextension/gdextension_cpp_example.html)
+* Install the Android SDK and NDK (For android builds)
 
 ### Building the extension
 
-To build the plugin invoke `scons` from the root directory of the project. The build product will in `build\bin`.  Invoking `scons example` will build the product and copy the binaries to the `example.gd\addons\tilt-five\bin` and `example.csharp\addons\tilt-five\bin` directories.
