Fix T69486: Reloading file in text editor marks file as modified

Cleanup: Add/use utility to remove regions

Fix empty file options region in regular editor

This would happen when opening a file browser as regular editor, opening
a temporary file browser from there (e.g. Ctrl+O) and cancelling the
operation.
In some cases this would cause most of the editor to be filled with an
empty operator options region:
* Go to Shading workspace
* File -> Append
* Cancel

Fix paint cursor drawing asserts

The new paint cursor (introduced in rBe0c792135adf) mixed 3d and 2d
drawing leading to asserts [e.g. when tablet pressure sensitivity was
enabled for size, see D5820 also].

We could get away with always drawing in 3D [using vertformat with
comp_len 3 / GPU_SHADER_3D_UNIFORM_COLOR / imm_draw_circle_wire_3d],
even if in the Image Editor, but this patch clearly separates what is
drawn in 3d and what is in 2d.
