Since the upstream of gstreamer-vaapi, the library is not a public shared
object anymore. But the EGL support depended on this dynamic library, so the
EGL support was broken.
This patch removes the dynamic library loading code and instantiates the
EGL display using either X11 or Wayland if available.

As gst-indent generated ugly code in these cases, this patch changes the used
idiomatic into other one.
No functional changes were introduced.

Add GstVaapiTextureEGL abstraction that can create its own GL texture,
or import a foreign allocated one, while still allowing updates from a
VA surface.
Add initial support for EGL to libgstvaapi core library. The target
display server and the desired OpenGL API can be programmatically
selected at run-time.
A comprehensive set of EGL utilities are provided to support those
dynamic selection needs, but also most importantly to ensure that
the GL command stream is executed from within a single thread.
