Plex+PyVista: Added transforms
- Now -view_pyvista_warp <f> warps by the active scalar
- Now -view_pyvista_clip <xl,xu,yl,yu,zl,zu> defines a clipping box

PetscSectionSelectFields_Private: allow larger blocking for fields with cell only dofs

this allows us to compute proper blocking for higher degree discontinuous fields

Plex+PetscFE: Fixes to allow embedded manifolds
- Add PetscFEGeomMode to describe geometry
- Reorganized PetscFEGeom
- PetscFEGeomCreate(), DMFieldCreateFEGeom() and DMSNESGetFEGeom() now take the PetscFEGeomMode
- J and invJ have dE dimensions
- f1, g1, g2, g3 have dE dimensions
- FIX the dim argument of all point function is really dE because it is used to index the gradients
- Clarified behavior of PetscFEGeomGetCellPoint()
- Now -dm_plex_coordinate_dim can change the coordinate dimension of a mesh created by Plex
- Implicit cell geometry must be used when dim != cdim

Plex: Fix DMSetCoordinateDisc() for isoperiodic boundaries

This reinstates the changes added in !5970 and removed in !6959.

tl;dr, `DMCreateInterpolation` (used in `DMSetCoordinateDisc`, and
`DMProjectCoordinates` before it) does not handle isoperiodic boundaries
correctly. !5970 replaced that code using `DMProjectFieldLocal` instead.
That was then removed in !6959. This is also discussed in issue 1506.
I initially made an MR in !7308, but that was on a fork. This commit is
on the PETSc repo itself.
