#14782: Automating supported params table for unary backward ops (#14894

)

### Ticket
#14782 

### Problem description
The table format needs to be updated in unary backward pybind to avoid
duplicating it for each op that is added.

### What's changed
- Updated supported parameters table format
- Reworded some descriptions
- Added clip_bw to rst file
- Move some binary backward ops from unary backward doc list.

### Checklist
- [x] [Post commit CI
