adaptive_cloth: run BKE_cloth_remesh() when remesh flag is on

adaptive_cloth: ui: add remesh option within shape

adaptive_cloth: `do_step_cloth()` should update the input mesh

adaptive_cloth: `clothModifier_do()` returns a new `Mesh` if simulation was successful

This is an important change that allows for remeshing operations in
the cloth simulator. `clothModifier_do()` returns the resulting mesh
if it was successful otherwise NULL.

adaptive_cloth: initial conversion of cloth modifier to `modifyMesh`
from `deformVerts`

Adaptive remeshing requires the mesh connectivity to change, so the
modifier should be of `eModifierTypeType_Nonconstructive` type and use
the `modifyMesh()` function instead of the `deformVerts()` function.

The next step is to make the `clothModifier_do()` function to take
advantage of the mesh given to it since now that mesh can be edited by
it and returned directly.
