tdf#121305 Increase accuracy of custom shape circle

The old implementation has used 4 segments and a questionable control
point distance. The patch changes this to use the common
implementation in basegfx. The method in basegfx is extended to allow
to set the start quarter, so that the custom shape circle can get the
same start quarter as it has before. The method descriptions in
basegfx are adapted to the current implementation.
