[rshapes] Fix drawing circle sectors (#6045)

Browse Source 
* [rshapes] Fix drawing circle sectors

Functions that draw a sector of a circle would keep drawing segments past a full rotation, which looked bad.

* [rshapes] Change `DrawCircleSectorLines()` and `DrawRingLines()`

`DrawCircleSectorLines()` and `DrawRingLines()` drew the cap lines even when drawing a full circle, which seems undesirable.
