refactor(search): De-couple baloo URL parsing logic from UI

Summary:
Extracts the logic that parses `baloosearch:` urls into a new model class. The parser logic itself is kept as is.
The search box UI is later updated using the model fields.

This refactor has been proposed by @bruns in the review of D24422, as it largely simplifies the unit tests and further expansion/improvements.

Test Plan:
No behavior changes.
Test case is added in the follow-up revision: D25258
