Juan Tejada cfdc401c54 update(extensions): Rename DraftStoreExtension and MessageStoreExtension
Summary:
- Rename DraftStoreExtension to ComposerExtension
- Rename MessageStoreExtension to MessageViewExtension
- Rename ContenteditablePlugin to ContenteditableExtension
  - Update Contenteditable to use new naming convention
  - Adds support for extension handlers as props
- Add ExtensionRegistry to register extensions:
  - ContenteditableExtensions will not be registered through the
    ExtensionRegistry. They are meant for internal use, or if anyone wants
    to use our Contenteditable component directly in their plugins.
  - Adds specs
- Refactors internal_packages and src to use new names and new ExtensionRegistry api
- Adds deprecation util function and deprecation notices for old api methods:
  - DraftStore.{registerExtension, unregisterExtension}
  - MessageStore.{registerExtension, unregisterExtension}
  - DraftStoreExtension.{onMouseUp, onTabDown}
  - MessageStoreExtension
- Adds and updates docs

Test Plan: - Unit tests
