We might want to document the properties, but not necessarily in this PR

I guess if this function is going away it doesn't matter

FYI test is falling because playwright only supports node 10+ but it's still node 8 |

A step on the long-ish path towards fixing #550
Also a step towards fixing #570
Proposed Changes
This PR removes the API for setting a drawable's rotation center and the
Skin.setRotationCenterfunction.It does not remove the API for setting a skin's rotation center when setting its contents.
To fix unit tests which previously called
Skin.setRotationCenter, it also adds arotationCentersetter (plus corresponding getter) toMockSkin, which the unit tests now use.I'm not expecting this to be merged right away--in case scratchfoundation/scratch-vm#2314 causes any regressions in the near future, it'll probably be beneficial to be able to revert that without having to re-add the rotation center API here as well.
Reason for Changes
In order to fix (no, GitHub, it doesn't close) #550, vector costumes' SVG viewboxes must depend on their rotation centers. Every time the viewbox of an SVG is set, its
<img>must be updated as well, which is a fundamentally asynchronous operation.As such, a synchronous API for setting a skin's rotation center after the skin is loaded is incompatible with the changes necessary for #550.
With scratchfoundation/scratch-vm#2314 merged, that synchronous API is no longer used and can be removed.
