Enabled 2D array textures
- Implemented mipmap generation and completeness checks for
Texture2DArray.
- Fixed texture parameters setters and getters along with
mipmap generation functions to use the proper 2D array
texture instead of the 3D texture for 2D array textures.
- Enabled the same path as 3D texture for 2D array textures
in the sampler.
- Added an address function for the w component, which
simply clamps the rounded value for 2D array textures and
adapted SamplerCore::computeIndices to this new behavior.
