ECP task updates

ECP/VTK-m Project Management


Fixed issues where WorldCoordiantesToParametericCoordinates and other operations would error out a worklet. Now have to deal with ErrorCode returned status.

Changed control-side portals to no longer lock ArrayHandles. Instead, you get an error logged if the portal is changed while you are still using it. Deadlocks should now be much harder to make.

Changing to GitLab continuous integration coming.

Can we get rid of streaming array handles and dispatching? This only works in very limited context and I expect it to never be used. (It may already be broken and we don't know it.) No one seems to have a problem with that.
