Update note regarding 3D MSAA and foveated rendering

godotengine#83976 added support for 3D MSAA on the Compatibility renderer, but it also mentions that on platforms other than Android, foveated rendering will not work if MSAA is enabled.

I removed the note saying that 3D MSAA is not supported on compatibility and added a comment mentioning that foveated rendering won't work on platforms other than android if 3D MSAA is enabled and added the alternative/equivalent for desktop.

 			Sets the number of MSAA samples to use for 3D rendering (as a power of two). MSAA is used to reduce aliasing around the edges of polygons. A higher MSAA value results in smoother edges but can be significantly slower on some hardware, especially integrated graphics due to their limited memory bandwidth. See also [member rendering/scaling_3d/mode] for supersampling, which provides higher quality but is much more expensive. This has no effect on shader-induced aliasing or texture aliasing.

 		<member name="rendering/anti_aliasing/quality/screen_space_aa" type="int" setter="" getter="" default="0">
 			Sets the screen-space antialiasing mode for the default screen [Viewport]. Screen-space antialiasing works by selectively blurring edges in a post-process shader. It differs from MSAA which takes multiple coverage samples while rendering objects. Screen-space AA methods are typically faster than MSAA and will smooth out specular aliasing, but tend to make scenes appear blurry. The blurriness is partially counteracted by automatically using a negative mipmap LOD bias (see [member rendering/textures/default_filters/texture_mipmap_bias]).
