This PR introduces the ability for users to switch between boolean
solvers while using the sculpt *Trim* tools (*Box Trim* & *Lasso Trim*)
much like the mesh boolean modifier and geometry node. Because the
*Exact* solver has performance issues with larger meshes, the *Fast*
solver is set to be the default.
In my very rough timing tests on my laptop on a mesh with **1.7m**
vertices, a *Trim* operation with the *Fast* solver finishes in roughly
20 seconds as opposed to still being in progress after five minutes
with the *Exact* solver.
Addresses part of #84229
