Add 'target' parameter for the 'draw' Texture's function in sdl2

[Hamzalopode]

Description

This idea came by wanting to draw multiple textures and scaling them in a renderer while not impacting the scale of the other texture already drew in the renderer.

Right now to do this you need to:

• Create a temp Texture and it target parameter to True.
• set the renderer.target equal to the temp Texture you just created
• draw your textures
• set renderer.target to None
• draw the temp Texture

Ideally we should have a target parameter in the draw function with type Texture to draw texture directly there without having the need to set the target to a texture then to None every time.

This Enhancement was proposed after the thread: 1114151550194040882 in the discord server with the help of @Matiiss

I think a better solution for this would be to make renderer.target a context manager, which would mean you don't have to reset to the original explicitly. It would also mean that texture.draw calls would not be the only functionality to retarget easily but all the draw and fill calls as well. Plus it looks more pythonic this way in my opinion.

with renderer.target(texture):
    other_texture.draw(...)
    renderer.fill_rect(...)

Note that at __exit__ the target would be set back to what it was before, which is not necessarily None (which I think makes sense, but I do want to point it out anyway).

I like it! Nice proposal, I will try to build a similar solution in my code base. Thanks
