egl: Enable EGL_EXT_client_extensions

Browse source 
Insert two fields into _egl_global to hold the client extensions and
statically initialize them:
    ClientExtensions // a struct of bools
    ClientExtensionString

Post-patch, Mesa supports exactly one client extension,
EGL_EXT_client_extensions.
