While developing an image in darkroom we might have set a cropping area, this commit
implements functionality to keep the cropped area if we change orientation via the
flip module.
Three parts in the codebase required additions without changing existing code.
1. `dt_develop_t` got two additions in cropping proxy,
`struct dt_iop_module_t *flip_handler` points to the crop module and is setup there.
We can't use `exposer` as the proxy because that is dynamically set in pixelpipe code
only if enabled and we want to change crop parameters even if crop is disabled.
`void (*flip_callback)` is the callback function changing crop parameters, defined in crop.
2. Orientation module uses the `flip_callback(self, orientation)` requesting changes in crop.
3. In crop we have `_crop_handle_flip()` as proxy `flip_callback` with proper logs about action.
- It gets the data from self `dt_iop_crop_params_t`,
- does the requested action,
- updates gui from parameters
- adds a new history stack entry (respecting the current `crop->enabled` status).

While developing an image in darkroom we might have set a cropping area, this commit implements functionality to keep the cropped area if we change orientation via the flip module.
Three parts in the codebase required additions without changing existing code so not expecting stability regressions.
