UI: de-duplicate mask context menu

- Use the clip mask context menu for the image editor.
- Remove redundant CLIP_MT_mask_handle_type_menu.
- Remove "Add" items (was only in image mask context menu)
as the convention is not to include these in the context menu.

Cleanup: move mask menu out of bl_operators

This file only defined a single mask menu, move the definition
along-side the other mask menus.

Cleanup: remove redundant dynamic tool expansion

The tools passed to _tools_flatten, _tools_flatten_with_tool_index
already have dynamic tool items expanded, so there is no need to check
for callable tool items.

Cleanup: pep8, unused vars, line length

Cycles: Fix one-tile UDIM rendering

The code checked for the presence of more than one tile before
substituting the tile number into the filename, so if a one-tile
UDIM was used (or all but one tile were culled), the substitution
was skipped and as a result the file was not found.

With this change, the code explicitly tracks whether substitution
is required, avoiding this problem.

This also fixes another problem: The Environment texture never
does substitution since it doesn't support UDIMs, but before the
syncing code still inserted the placeholder into the filename if the
user selected a tiled background image.

Cleanup: whitespace

GPencil: First step to fix damaged UI by Brush panel refactor done in master

The patch done in master was done before the Sculpt and Weight brushes were real brushes and also before the Vertex Paint mode was implemented. As result of that, the merge of master has broken almost all panels of brushes and all Vertex Paint mode.

This commit only fix part of the damages.
