• Build script enhancements including {stdin, stderr} output logs.
• Added eclipse temurin Open-JDK-17 to the github runner images.
• Documentation for the native side api.

@Ali-RS I am done laying out the base api and the documentation, please give them a look before merging.

• About other methods memorySet(), memoryMove(), and memoryCopy() there will be techdemos showing their usages.
• As for TestLibrary.java class it was for prototyping and the API shouldn't have a main runnable method, and the jme3-testalloc will have a list of techdemos later on.
