Implement EGL_ANGLE_explicit_context

Implementation of EGL_ANGLE_explicit_context. Includes new libGLESv2 entry
points and exports, libANGLE entry points, extension declarations for
eglGetProcAddress, and unit tests. Autogeneration scripts have been
modified to produce entry points, exports, eglGetProcAddress function
table, extension function pointers, and function declarations.
