mojo: Fix window resizing in mojo_sample_app and mojo_demo_launcher.

These ended up having different bugs in different apps. In the
mojo_sample_app, we didn't pass a glResizeCHROMIUM() call on resize. In
mojo_demo_launcher, we weren't plumbing events from the aura window
hierarchy to the ServerView correctly.
