Based on feedback from users this PR brings back the most commonly used
brush shortcuts in sculpt mode. Essentially reverting some of the
changes from #108712
There are multiple reasons behind this decision:
- Anyone coming from a previous version will instinctively reassign the
brush shortcuts to the same keys as before, introducing shortcut
conflicts as a result. Having the shortcuts there by default makes this
case less likely as it makes available brush shortcuts more obvious.
- The default `paint.brush_select` operator is hard to set up manually
and is offering behavior that isn't available with the
`wm.tool_set_by_id` which is far easier to create from the UI
- There are too many brushes available to know which ones are the most
common ones.
There are some additional changes:
- `S` is now used for the Smooth brush.
- Draw brush is now assigned to `V` to avoid conflicts on `X`.
- `Shift T` is using the Scrape instead of Flatten brush.
- `C` is using the Clay Strip instead of Clay brush.
Removing the brush shortcuts can be revisited later once the brush
management is overhauled.
