Fix globe terrain holes at poles

[kubapelc]

• Fixes Mesh is broken near the pole on globe with terrain #4984
• Fixes Globe with/without terrain can zoom too far out #4990

Also fixes an artifact when globe terrain was zoomed out too much. Brings back the globe/terrain/fill-planet-pole test (see #5194), it should no longer be unstable.

Does it fix the following issue as well?

• Globe with/without terrain can zoom too far out #4990

Does it fix the following issue as well?

It fixes the geometry sticking out of the planet, but not the zoom controls/behaviour.

[HarelM]

I'll mark it as fixed as I think this is the main concern in this issue, for the problem of min zoom another issue can be opened if someone cares about it enough...

[HarelM]

Thanks!!

I've just noticed that the pole mesh is also used on mercator and it doesn't look too good, I'll try to fix that.
