iOS support

[joliver82]

• Added jme3-ios-native library mostly based on old native iOS code prepared to work with both MOE and RoboVM (robovm is still WIP)
• Modified jme3-ios adding buffer allocator and proper getPlatform method

Pending to add jme3-ios-native library to be uploaded to maven. Any help is appreciated

You should probably write at least one test for this.

If gradlew install installs the library to your Maven Local repository, then I expect gradlew release will upload it to the correct staging repo.

Thanks for the comments

@codex128 , OK, I would write some, but... Which kind of tests do you want me to do? Also, how could I make them run either when compiling locally or in github actions if this code is intended to run only on iOS?

@stephengold , checked and the artifact is saved properly to mavenLocal. I had to make a small change so the jar is properly created when running "gradlew install". Thanks for the tip
