Ben Gotow b4434f6617 fix(focus): Remove focusedField in favor of imperative focus, break apart ComposerView
Summary:
- Removes controlled focus in the composer!
  - No React components ever perfom focus in lifecycle methods. Never again.
  - A new `Utils.schedule({action, after, timeout})` helper makes it easy to say "setState or load draft, etc. and then focus"
  - The DraftStore issues a focusDraft action after creating a draft, which causes the MessageList to focus and scroll to the desired composer, which itself decides which field to focus.
  - The MessageList never focuses anything automatically.
- Refactors ComposerView apart — ComposerHeader handles all top fields, DraftSessionContainer handles draft session initialization and exposes props to ComposerView
  - ComposerHeader now uses a KeyCommandRegion (with focusIn and focusOut) to do the expanding and collapsing of the participants fields. May rename that container very soon.
- Removes all CommandRegistry handling of tab and shift-tab. Unless you preventDefault, the browser does it's thing.
- Removes all tabIndexes greater than 1. This is an anti-pattern—assigning everything a tabIndex of 0 tells the browser to move between them based on their order in the DOM, and is almost always what you want.
- Adds "TabGroupRegion" which allows you to create a tab/shift-tabbing group, (so tabbing does not leave the active composer). Can't believe this isn't a browser feature.

Todos:
- Occasionally, clicking out of the composer contenteditable requires two clicks. This is because atomicEdit is restoring selection within the contenteditable and breaking blur.
- Because the ComposerView does not render until it has a draft, we're back to it being white in popout composers for a brief moment. We will fix this another way - all the "return unless draft" statements were untenable.
- Clicking a row in the thread list no longer shifts focus to the message list and focuses the last draft. This will be restored soon.

Test Plan: Broken
