Monogame: PlatformClear inconsistent accesability level

[bjornenalfa]

GraphicsDevice.PlatformClear and GraphicsDevice.PlatformPresent are public when targeting OpenGL or Web but private when targeting DirectX. This can lead to errors when switching platforms or potentially cause a System.MethodAccessException when using assemblies built for a different platform.

What version of MonoGame does the bug occur on:

• Develop

What operating system are you using:

• Windows

What MonoGame platform are you using:

• DesktopGL, WindowsDX

Thanks for reporting this @bjornenalfa .... PlatformXXXX shouldn't be public at all on any platform. Those should all be internal/private APIs.

If someone gets a chance to fix this please submit a PR.

Alright, I've got a free minute or two. May as well take a stab.

The same fix is needed for GraphicsDevice.Web.cs

Additionally there's a public Mouse.PlatformSetCursor(...)
in Mouse.Default.cs and Mouse.Windows.cs

The web backend is just stubs, its not even getting compiled by the build bot, the real one lives in my fork.

@harry-cpp - Still the docs show any public APIs like that. So it would be good to fix it just to avoid it appearing in the docs.
