Fix the SDL3 GLProfileFlag enum

[Yakvi]

In vendor:SDL3 package, there's currently a notable discrepancy between the SDL_GL_CONTEXT_PROFILE_xyz defines in SDL_video and as specified in sdl3_video.odin:

SDL_VIDEO:

#define SDL_GL_CONTEXT_PROFILE_CORE           0x0001  /**< OpenGL Core Profile context */
#define SDL_GL_CONTEXT_PROFILE_COMPATIBILITY  0x0002  /**< OpenGL Compatibility Profile context */
#define SDL_GL_CONTEXT_PROFILE_ES             0x0004  /**< GLX_CONTEXT_ES2_PROFILE_BIT_EXT */

sdl3_video.odin:

GLProfileFlag :: enum Uint32 {
	CORE          = 0, /**< OpenGL Core Profile context */
	COMPATIBILITY = 1, /**< OpenGL Compatibility Profile context */
	ES            = 2, /**< GLX_CONTEXT_ES2_PROFILE_BIT_EXT */
}

This error results in unintended behavior, even leading to crashes when used inside a Darwin environment. this PR aims to rectify said discrepancy by enumerating the values as intended.

So this is not a bug since the bit_set is meant to be used for the flags NOT the enum.

Right, I got it now. I was confused since SDL2 implementation didn't use the bit sets. Thanks for clarifying!
