minui: Remove the default and copy ctors for GRSurface.
As well as all the derived classes. Instances must be created with
Create(). A default copy ctor would mess up the ownership of the
mapped or allocated buffer in these classes, so that has been explicitly
removed.
Test: mmma -j bootable/recovery
Test: Run recovery_unit_test on marlin.
Test: `Run graphics test` on blueline.
