video_core: fixed arithmetic overflow warnings & improved code style
- Fixed all warnings, for renderer_opengl items, which were indicating a possible incorrect behavior from integral promotion rules and types larger than those in which arithmetic is typically performed. - Added const for variables where possible and meaningful. - Added constexpr where possible.
