Add a render process mojo interface exposed to the browser for
receiving process-wide spellcheck control and updates from the
browser process.

Fold the enable IPC into the Initialize() mojo API (the enable
IPC was only ever called right after an Init IPC) by adding an
|enable| argument. Mojo does not support set<> so use vector<>
instead on the mojo APIs. Use a binding set on the server-side
to automate mojo request disconnect and clean-up.

Update the browser test to use mojo instead of IPC in the mock
renderer and add a test for a custom dictionary update. Change
the InitSpellcheck helper: spellcheck->InitForRenderer() isn't
needed (creating a SpellcheckService does that for us).
