I18n: Extract and disambiguate a few messages

Extract
- Cycles denoiser enum.
- Extensions user preferences UI.
- Node operator poll message from new node function.

Improve
- Split "(Enabled|Disabled) on startup, overriding the preference."
into two messages.

Disambiguate
- "Add" when describing the action of adding something should use the
  Operator context.
- "Dimensions", in noise textures.
- "Transform" as a noun, the matrix transform type of Geometry Nodes,
  as opposed to the verb to move things in space.
- "Parent" as a noun or verb (the parent of an object, to parent an
  object to another).

Some issues reported by Satoshi Yamasaki, deathblood, and Gabriel Gazzán.
