Add surrounding text to EditorInfo to speed up IME startup
Previously when IMEs want to get initial input text for advanced
prediction featues, it will take up to three IPC calls. Once we provide
the initial text in the EditorInfo object, it would be available right
after the input connection setup and no IPC overheads will be
introduced.
