Extend the CIRCLE statement to accept an optional trailing ,F parameter
that draws a filled ellipse using AreaEllipse(). Only valid for whole
circles (default start/end angles); arcs with fill produce error 83.

Runtime: _fillellipse routine in gfx.s using AreaEllipse + AreaEnd
with TmpRas setup/cleanup following the existing _areafill pattern.

Compiler: circle() in gfx.c parses ,F after aspect, emits jsr
_fillellipse for full ellipses or error 83 for arcs.
