Dylan Hurd 96a72828be feat(core) ModelInfo.model_instructions_template (#9597)
## Summary
#9555 is the start of a rename, so I'm starting to standardize here.
Sets up `model_instructions` templating with a strongly-typed object for
injecting a personality block into the model instructions.

## Testing
- [x] Added tests
- [x] Ran locally
