Uriel Doyon b9444f338f Added support for UVolumeTexture and UTexture2DArray streaming. ...

Texture 2D array streaming is implemented through FTexture2DArrayMipAllocator_Reallocate
Volume texture streaming is implemented through FVolumeTextureMipAllocator_Reallocate.
New generic stream out implementation in FTextureStreamOut.

Fixed different issues in FTexture2DMipDataProvider_IO relatively to optional bulks and IO errors.

Added UTexture::GetSurfaceDepth() for 3d textures.
Added UTexture::GetSurfaceArraySize() for array textures (where cubemaps return 6).

Moved UTexture2D::CancelPendingTextureStreaming() and UTexture2D::LevelIndex to UTexture.

Renamed UTexture2DArray::GetNumSlices() to UTexture2DArray::GetArraySize().

Fixed missing "virtual" keyword in base class UTextureMipDataProviderFactory.

Updated the texture editor UI so that it shows Texture2DArray array sizes and Texture3D depth.
Unified the UI for cubemaps so that it shows as an array with size 6.

Reimplemented "LODGroups" command to make it coherent with latest changes.
