Introduce InputMethodUtils#splitEnabledImeStr()

This is a follow up CL to my previous CL, which added

  InputMethodUtils#getEnabledInputMethodIdsForFiltering() [1]

as an internal utility method.  This CL extracts out its main logic as

  InputMethodUtils#splitEnabledImeStr()

with a unit test so that we can reuse the same functionality in
subsequent CLs.

This is a mechanical cleanup. There must be no observable behavior
change.
