[OpenVG] Add (EGL) surface/context management
​https://bugs.webkit.org/show_bug.cgi?id=33403

The foundations for a new OpenVG port.

OpenVG is not tied to EGL per se, EGL just happens to be
the only usable backend for OpenVG state and painting
at the time of writing.

The purpose of the SurfaceOpenVG class is to provide
an EGL-independent interface for OpenVG-specific code.
The EGLDisplayOpenVG class takes care of keeping track
of EGL displays, surfaces and contexts. It also makes
sure that all created contexts are interoperable, and
that different surfaces use a single context if possible.

• platform/graphics/openvg/EGLDisplayOpenVG.cpp: Added.
