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.
