Ref D14069
In the original design draw engines had to copy with a limitation that
they were not allowed to reuse complex data structures between drawing
calls. Data that could be reused were limited to:
- GPUFramebuffers
- GPUTextures
- Memory that could be removed calling MEM_freeN (storage list)
- DRWPass
This is fine when the storage list contains arrays or structs but when
more complex data types (vectors, maps) etc wasn't possible.
This patch adds instance_data that can be reused between drawing calls.
The instance_data is controlled by the draw engine and doesn't need to
be limited as described above.
When an engines stores instance_data it must implement the
`DrawEngineType.instance_free` callback to free the data.
The patch originates from eevee rewrite. But was added to master as the
image engine rewrite also has a need for it.

This is a simple engine used only to debug the texture of select ids.
It is only used when the `WITH_DRAW_DEBUG` option is enabled and the
debug value is 31.
