I18n: disambiguate a few translations

- Keying (keyframe insertion)
- Roughness (particle children)
- New image, collection, text (in menus)
- Parents (particles)
- Wrap (text)
- Light (add menu)
- Empty (volume add menu)
- Empty (empty add menu)
- Cycles (f-curve modifier)
- Drag (workspace tool type)
- Power (light intensity)
- Power (math nodes)

This last change also moves all math operations in nodes to the
ID_nodetree context. It's needed only for some operations, but we
can't be more granular here.

Also...

- Fix context extraction for interpolation mode headers in F-Curves
  and GPencil interpolation operator
- Enable new translation: "Slot %d" in image editor
- Fix an English message in the node editor:
  "Replace the input image's alpha channels by..." -> channel
