Sculpt: Add Lasso Hide tool

This commit adds the `SCULPT_OT_hide_show_lasso_gesture` and the
corresponding Lasso Hide tool.

* Exposes the selection type for both the lasso and box hide tools
  as a option in the header
* Adds functionality into `sculpt_gesture.cc` for handling lasso
  selections with the `Outside` selection type

For `SelectionType::Outside`, the current implementation opts to not
do any filtering on the PBVH node level due to cases where the node
is mostly covered by a single gesture.

Addresses one of the tools in #80390
