search: Add support for case-sensitivity pattern items (#34762)

This Pull Request introduces support for pattern items in the buffer
search. It does so by splitting the `query` methods into two new
methods:

- `BufferSearchBar.raw_query` – returns the text from the search query
editor
- `BufferSearchBar.query` - returns the search query with pattern items
removed

Whenever the search query is updated, processing of the
`EditorEvent::Edited` event ends up calling the
`BufferSearchBar.apply_pattern_items` method, which parses the pattern
items from the raw query, and updates the buffer search bar's search
options accordingly. This `apply_pattern_items` function avoids updating
the `BufferSearchBar.default_options` field in order to be able to reset
the search options when a pattern items is removed. Lastly, new pattern
items can easily be added by updating the `PATTERN_ITEMS` array.
