WIP: Ocean System

[anandbarai09]

Todo
Ocean Shader(In Progress, Current Shader is not good looking and has many problems),
Ocean Physics.

Done :
Ocean Clipmap
Ocean3D (Ocean3d node , Ocean3DStorage, Ocean3DMaterial) (will require some cleanup)

Ocean Clipmap looks identical to GeoClipMap. You should just use GeoClipMap to generate a second clipmap. We put it into a separate class so it can be reused. If there are particular custom options you need in the ocean mesh, GeoClipMap can be modified.

ok I will create a new function in generate_ocean() because it uses skirt mesh and terrain3d's clipmap does not use skirt.

@anandbarai09 It would be helpful if you could share screenshots

I'm sure screenshots can wait until Op has something implemented and working.

Op, like my comment on GeoClipMap, you're duplicating a lot of classes. That is unnecessary. Change the existing classes or derive from them as needed. Reuse code religiously. Utilize the inheritance model within C++. You can dramatically reduce the amount of code, which will make this PR easier to write and maintain as you get closer to completion.

Even the change you made to GeoClipMap is unnecessary. You don't need to duplicate an entire function just so you can have skirts. Instead add a parameter to the function and add skirts if that parameter is true. Your 400 lines of changes to this class will be reduced down to 20.
