I18n: extract and disambiguate a few messages

Extract:
- Compositor error messages.
- `bUnitDef`s were broken after cleanup commit 2b77cd726d. Since each
  unit's "display name" is now preceded by a consistent "name_display"
  comment, the regex which extracts the unit is greatly simplified.
  It now relies on the presence of the comment instead of the struct
  order.
- "Preset" menu and "Apply Preset" button from the curveprofile
  template.
- Operator labels from the catalog context menu.

Disambiguate:
- "Bake Data": can mean "Which data to bake" (verb), or "The data that
  were baked" (noun).
- "Cache" in the Simulation Nodes panel is a verb, not a noun.
- "Mix" in the snapping menu is a noun, not a verb.
- "Top" and "Bottom" can mean the upper part of an object or the
  highest point or element of something like a menu or list.
