Ocean Modifier: Add viewport resolution

Following work done in 2.83, the resolution control is now a real
level-of-detail parameter. It is now useful to be able to set the
resolution for display independently from render. This is true for
both mesh generation and mesh deformation modes.

For compatibility with old scenes, resolution is retained and is the
render resolution. Old modifiers loaded have the value of resolution
also applied to viewport resolution. This allows newer modifiers to
be used in older versions without trouble
