Enable GL on Wayland for wx 3.2+, no vsync.

wxWidgets 3.2+ has experimental `wxGLCanvas` support for Wayland EGL,
enable it for those versions.

The `glXQueryExtensionsString()` method for enabling or disabling vsync
does not work on Wayland currently, so it's disabled.

TODO: Enable/disable vsync on Wayland EGL.

Fix #1028.
