Revert "Implement Skew in Node2D"

Browse Source 
This reverts commit 7f61710183.

See #38868, in its current implementation a small skew value might end up
serialized to scene files due to floating point precision errors, which is
detrimental to VCS.

This can be cherry-picked anew once a fix for #38868 has been found.
