Once again those crappy weirdos IDs with their crappy weirdos 'loopback'
pointers...
This is a quick hack for now, think id_copy needs to be reworked a bit
to supported re-entrant sub-ID copying (also an issue with nodes I bet).
Adds the invert vertex group option to the Curve modifier.
Adds a short flag and char pad to the Curve modifier DNA. Passes the flag into the curve_deform_verts function as the weight values are found there and not in the modifiers .c file.

Adds the invert vertex group option to the Lattice modifier.
Adds a short flag and modifies the existing char padding for the correct amount.
Adds a .invert_vgroup to the LatticeDeformUserdata.
Passes the flag into the lattice_deform_verts function where the weights around found and used.
For the other calls of lattice_deform_verts function they pass in NULL for the flag in the same way they pass NULL for the vgroup name.

Use the term "AFTER" instead of "OFS" since it wasn't obvious these
macros operate on everything after the struct member passed.
Avoid casting to non-const types when only reading.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.

This modifier only uses mesh to get vgroup, which is only needed in case
modified object is indeed a mesh! Building a mesh from curve here is not
only useless and time-consuming, it will also easily fail the assert
about same number of vertices!
Also, use MOD_get_vgroup() helper in modifier code itself and pass
reluting MDeformVert & index to BKE_curve's curve_deform_verts(),
this is simpler and avoids duplicating vgroup handling code.
Also fixes crash when used on lattice.
Related to T57972.
Make it more reliable and predictable way of getting pointer to
an original mesh which came from copy-on-write engine.
Related change: made it (hopefully) more clear name for flags.
