Update usage of 'sinf()' and 'cosf()' to be correct

[RokasPuzonas]

Changes for fixing #3180

Besides swapping sinf() and cosf(), the vertex order for quads and triangles was updated, so they would be visible.

Here is an example that I used to test if my changes were good, this includes all functions that were updated:

// example.cpp
// Compiling:  g++ example.cpp -lraylib
#include <raylib.h>
#include <raymath.h>

int main() {
	InitWindow(800, 800, "Reproduction");
	SetTargetFPS(60);

	while (!WindowShouldClose())
	{
		BeginDrawing();
		ClearBackground(RAYWHITE);

		float angle = (int)(GetTime()*100) % 360;

		DrawCircleSector({ 150, 100 }, 50, 0, angle, 5, BLACK);
		DrawCircleLines(150, 100, 50, BLACK);

		DrawCircleSectorLines({ 300, 100 }, 50, 0, angle, 5, BLACK);
		DrawCircleLines(300, 100, 50, BLACK);

		DrawRing({ 450, 100 }, 25, 50, 0, angle, 5, BLACK);
		DrawCircleLines(450, 100, 50, BLACK);

		DrawCircleGradient(600, 100, 50, BLUE, RED);

		DrawCircleLines(150, 250, 50, BLACK);
		Vector2 line_dir = { 50, 0 };
		DrawLine(150, 250, 150 + line_dir.x, 250 + line_dir.y, BLACK);
		line_dir = Vector2Rotate(line_dir, DEG2RAD*angle);
		DrawLine(150, 250, 150 + line_dir.x, 250 + line_dir.y, BLACK);

		DrawEllipse(300, 250, 25, 50, BLACK);

		DrawEllipseLines(450, 250, 50, 25, BLACK);

		DrawRingLines({ 600, 250 }, 25, 50, 0, angle, 5, BLACK);
		DrawCircleLines(600, 250, 50, BLACK);

		DrawRectangleRounded({ 100, 350, 100, 100 }, 0.4, 5, BLACK);

		DrawRectangleRoundedLines({ 250, 350, 100, 100 }, 0.4, 5, 1, BLACK);

		DrawRectangleRoundedLines({ 400, 350, 100, 100 }, 0.4, 5, 3, BLACK);

		DrawPoly({ 600, 400 }, 5, 50, 0, BLACK);

		DrawPolyLines({ 150, 550 }, 5, 50, 0, BLACK);

		DrawPolyLinesEx({ 300, 550 }, 5, 50, 0, 10, BLACK);

		EndDrawing();
	}

	CloseWindow();

	return 0;
}

@RokasPuzonas Thank you very much again for this great improvement!
