Fix noiselib to properly compile on android (float literals). Also fixed NoiseLib.glsllib code indent

[joliver82]

A quick PR to fix noiselib on android (and possibly other GLES systems). When using literals it's required to add decimals when type of the function called is float, otherwise depending on the device we may get errors when compiling the shader:

S0001: No matching overload for function 'Noise3D' found

Improved GLSLCompat to avoid issues in legacy GLES devices (GLSL<130) not having sampler2DArray type

🖼️ Screenshot tests have failed.

The purpose of these tests is to ensure that changes introduced in this PR don't break visual features. They are visual unit tests.

📄 Where to find the report:

• Go to the (failed run) > Summary > Artifacts > screenshot-test-report
• Download the zip and open jme3-screenshot-tests/build/reports/ScreenshotDiffReport.html

⚠️ If you didn't expect to change anything visual:
Fix your changes so the screenshot tests pass.

✅ If you did mean to change things:
Review the replacement images in jme3-screenshot-tests/build/changed-images to make sure they really are improvements and then replace and commit the replacement images at jme3-screenshot-tests/src/test/resources.

✨ If you are creating entirely new tests:
Find the new images in jme3-screenshot-tests/build/changed-images and commit the new images at jme3-screenshot-tests/src/test/resources.

Note; it is very important that the committed reference images are created on the build pipeline, locally created images are not reliable. Similarly tests will fail locally but you can look at the report to check they are "visually similar".
