UI: expose mesh conversion in apply menu

The mesh convert operator can 'freeze' a mesh
(WYSIWYG, modifiers, shape keys etc).
However its not very obvious that the way to perform this
operation is to convert a mesh to a mesh.

Expose this as 'Visual Geometry to Mesh' in the 'Apply' menu,
since this is where users might expect to see it.
