ChromeOS Developer 284bf5549a firmware: Refactor and clean up ec_sync ...

Previously, the EC software sync process called VbDisplayScreen() from
several function calls deep.  Refactor software sync so that the UI
decisions are at a higher level (in ec_sync_all.c) and isolated from
the low-level EC software sync functionality (in ec_sync.c).

This is one in a series of changes which are more clearly separating
out the UI, to make it easier to support multiple UI across a range of
devices.
