feat: Add new Pathfinder 2e Creature layout (#436)

[miscoined]

Pull Request Description

Add a new default Pathfinder 2e Creature layout. See #436 for rationale and background. This adds this as a new layout, without replacing the existing Basic layout. I'm opening this as a draft PR for now until I finish adding documentation and layout restoration functionality - I thought early feedback would be useful in this case.

Changes Proposed

• [x] Add a new Pathfinder 2e Creature Layout
• [x] Update Pathfinder 2e CSS from the upstream repo
• [ ] Add documentation for the new layout
• [ ] Add/update the default layout block for layout restoration functionality

Related Issues

Progresses #436.

Hey @miscoined, this looks great. Is this meant to slot into existing PF2e creature stat blocks used by the TTRPG share?

Sorry I let this sit for so long; been a very busy summer. I appreciate the work you have been doing.
