GLArrayData*: Shorten methods (*API Change*), use proper constructor and finalize immutables, add growthFactor (default golden ratio 1.618), add getCapacity*() and printStats(..)

The growthFactor becomes essential for better growth behavior and can be set via setGrowthFactor().

The other changes were merely to clean up the GLArrayData interface and its 4 implementations.

Not great to change its API, but one name was misleading ['getComponentCount' -> 'getCompsPerEleme'],
so overall .. readability is enhanced.

Motivation for this change was the performance analysis and improvement of our Graph Curve Renderer.
