Removed SDL_GL_BindTexture() and SDL_GL_UnbindTexture()

Browse source 
Now that we have the OpenGL texture properties, you can directly bind them yourself.

Fixes https://github.com/libsdl-org/SDL/issues/2124

/**
* Bind an OpenGL/ES/ES2 texture to the current context.
*
* This is for use with OpenGL instructions when rendering OpenGL primitives
* directly.
*
* If not NULL, `texw` and `texh` will be filled with the width and height
* values suitable for the provided texture. In most cases, both will be 1.0,
* however, on systems that support the GL_ARB_texture_rectangle extension,
* these values will actually be the pixel width and height used to create the
* texture, so this factor needs to be taken into account when providing
* texture coordinates to OpenGL.
*
* You need a renderer to create an SDL_Texture, therefore you can only use
* this function with an implicit OpenGL context from SDL_CreateRenderer(),
* not with your own OpenGL context. If you need control over your OpenGL
* context, you need to write your own texture-loading methods.
*
* Also note that SDL may upload RGB textures as BGR (or vice-versa), and
* re-order the color channels in the shaders phase, so the uploaded texture
* may have swapped color channels.
*
* \param texture the texture to bind to the current OpenGL/ES/ES2 context
* \param texw a pointer to a float value which will be filled with the
* texture width or NULL if you don't need that value
* \param texh a pointer to a float value which will be filled with the
* texture height or NULL if you don't need that value
* \returns 0 on success or a negative error code on failure; call
* SDL_GetError() for more information.
*
* \since This function is available since SDL 3.0.0.
