Combined caching and thumbnail drawing code

Involves modification to the image rendering, caching and drawing. The
thumbs are fixed to 256 max size, the caching is limited in number
and the overall look of the thumbnails is proper (no incorrect clipping).

Maniphest task : T89143

Differential Revision: https://developer.blender.org/D11718

Thumbnail Code Cleanup

Improved from the hacky way of cropping using the same process for scaling
to thumb size to using dedicated IMB_rect_crop method. Cleaned up
unnecessary code and variables.

Strip thumbnail drawing Fix : Thumbnails crop to exact width of strip

The end thumbnails crop to the exact left and right edges of the strip.
The previous version had poor clipping of thumbnails.

Cache limit : Set a limit of 1000 thumbs that can be cached giving around
160MB of memory for thumbs. Once the limit is reached, all cached thumbs
before and after the current view x limits are removed.

Pushed all thumbnail rendering and caching code to new function. Cleaned up
all conditions using context->is_thumb.

Cleanup : Fixed the thumbnail size to max 256 for any dimension. Removed
scaling and cropping from UI - hard scale to match result dimensions and
no crop. Removed any further preprocessing as the thumbnails should represent
original source footage. any rotation or tranform could confuse users as to
what the strip original footage was.
