Support remote installation of extensions and apps.

To enable this support, the following things are changed:
* ExtensionSyncData, and the ExtensionSpecifics protobuf have a new
  remote_install field, to mark a remotely installed extension.
* A new DISABLE_REMOTE_INSTALL reason is added to track this state
  locally.
* CrxInstaller::allow_silent_install is changed from a bool to a
  three-state enum, where the options are:
    - install after showing a permission prompt,
    - install and grant all permissions without a prompt and
    - install without a prompt and don't grant any permissions
* AddExtensionDisabledError is modified to keep track of the disable
  reasons, and change the text that is displayed accordingly.
* ExtensionInstallPrompt has a new prompt type with different text
  for remotely installed extensions.
