Refactor base/ime components and dependencies for ozone
plaform integration to avoid cyclic dependencies.

- Groups ui/base/ime common types into their own GN component
  (ime_types) to break a dependency cycle that ozone ime context
  integration would cause on ChromeOS.
- Groups some of ui/base/ime/linux interfaces into their own GN
  component (ime_linux) to break a dependency cycle that ozone
  ime context integration would cause on ChromeOS.
- Move chromeos source files under is_chromeos flag to avoid
  depending them when chromeos is not used, but ime is needed
  (kudos to msisov@igalia.com).
