egl: implement callbacks for defining custom EGL attributes 
Depending on the underlying EGL library, it may be desirable to
conditionally set some specific EGL attributes depending on available
extensions and other application state.

SDL's EGL usage makes this a little bit complicated because:

- there are multiple functions used to set up a working EGL context
- some of these functions take different types of EGL attributes
  (EGLAttrib vs EGLint)
- the EGL extension list before creating an EGLDisplay differs from the
  extension list after (i.e. display vs client extensions)
- all of the above happens in a single SDL_CreateWindow call

This leaves no place for the application to discover what EGL extensions
are available and provide custom attribute lists.

Until now, if a developer wants to add a custom EGL attribute for
eglGetPlatformDisplay, eglCreateWindowSurface or eglCreateContext, they
needed to patch SDL itself. This is very undesirable, since such
developers would have to disable the SDL dynapi in order to maintain
compatibility with their needs.

This patch implements some callbacks which developers can use to
dynamically generate custom EGL attributes for SDL to use during
SDL_CreateWindow.
