This patch will show textures in the image editor with the maximum
available resolution determined by the GPU Hardware/Driver.
Currently the size is limited by the user preference texture size limit.
An image user can set the `IMA_SHOW_MAX_RESOLUTION` flag to request
gpu textures in the max supported resolution. When this flag isn't
set the gpu texture is limited by the user preference setting.
When the gl resolution limit is disabled the GPU texture is always
created for the max supported resolution.

Crash is related to the definition of the GL_MAX_TEXTURE_SIZE. OpenGL does not clearly
defined `GL_MAX_TEXTURE_SIZE` exactly means. Both on AMD and NVIDIA we have issues with
huge textures that they don't get created even if they are smaller. (See {D9530} for
research).
This patch will try to create the texture in a smaller size when the texture creation
failed.

We should create a solution that doesn't need downscaling. For this specific case ARB_sparse_texture might help to create cleaner code, but you still have to commit the whole image what introduces several draw calls. Other improvement is to optimize the scaling; current implementation isn't optimized for performance.

`imb_gpu_get_data` could reuse `data_rect` when it was already in used (double alloc).
making the first use leak. This was detected after enabling OpenGL Texture

This is to modernize the API:
- Add meaningful name to all textures (except DRW textures).
- Remove unused err_out argument: only used for offscreen python.
- Add mipmap count to creation functions for future changes.
- Clarify the data usage in creation functions.
This is a cleanup commit, there is no functional change.

This is in order to disolve GPU_draw.h into more meaningful code blocks.
All the Image related function are in `image_gpu.c`.
All the MovieClip related function are in `movieclip.c`.
The IMB module now has a connection with GPU. This is not strickly
necessary and the code could be move to `image_gpu.c` if needed.
The Image garbage collection is also ported to `image_gpu.c`.
