jak2/3: implement ocean envmap (#4303)

Browse Source 
Implements the envmap for the ocean generated by
`ocean-method-89`/`ocean-method-88`.

While the resulting envmap looks accurate compared to PCSX2 in
Renderdoc, the end result does not seem 100% identical, but it is a big
improvement over the default placeholder texture.

Closes #3417
