OpenGL: refactor UI_draw_roundbox functions

Each function takes a bool (filled vs outline) and a color. We already had multiple ways of passing color in; these are still here. Special variant for anti-aliasing.

- took GLenum out of interface
- removed UI_RB_ALPHA flag (only one place really used it)
- use exact vertex count
- removed redundant state changes (BLEND, LINE_SMOOTH)
