Jehan 90d0a7f628 app, menus: move "GEGL Operation" from Tools to Filters > Generic menu. 
See the discussion in #5339. Basically this is now technically a tool
(i.e. a child class of GimpTool) and tools can be activated anytime,
even when no images are opened, i.e. when they are useless (for instance
paint tools). Filters on the other hand were historically only
activatable with opened images. With time, tools and filters difference
got slimmer (until there are technically none nowadays where GEGL ops,
levels or curves are implemented as GimpTool too) if not only a
conceptual difference.

Since here GEGL Operation is really more on the "filter" side, let's
just move it to the "Filters > Generic" submenu, just next to "GEGL
Graph", also removing the mention of it being a "tool" from the help
message.
Then I will merge !402 for it to be (in)active depending on images, as
other filters do.
