Android Basic Support

[pavly-gerges]

This PR adds the following:

• Bash build script for android.
• Android compiling task.
• UnSupportedSystemError: that is thrown when an unsupported system has been detected.
• A github runner compile and upload jobs for android.

And modifies the following:

• Gradle buildSrc: support script command args.
• NativeVariant: added the Android to the systems.
• NativeBinaryLoader: added a check for android and other unsupported systems.
• Github runner jobs to the new gradle tasks names.

Tested on android and got this exception, as a result of the System.getProperty("os.name") on android is being also Linux:

The last commit, should resolve this exception; because it checks first if the VM is a dalvik on a linux system (that's android for sure).
