vgacon: Use vt_cursor_{start,end}()

Replace vgacon's custom cursor metrics with the shared helpers
vc_cursor_start() and vc_font_cursor_end(). Note that the _end()
function returns the index of the scanline below the cursor, while
VGA hardware expects the cursor's final scanline. Hence vgacon
subtracts 1 from the end value.

The cursor shapes remain mostly unchanged, except that non-underline
cursors now also use the glyph's top-most and bottom-most scanline.
This follows the style used by fbcon.
