[Zucchini] Move Zucchini from /chrome/installer/ to /components/.

(Use "git log --follow" to see older revisions of files).

/components/ is the most logical place to put Zucchini, which only
depends on /base and /testing/gtest. This move also enables Zucchini to
be used by the Component Updater. Details:
- Move all files; run the following to change deps and guards:
  sed 's/chrome\/installer/components/' *.cc *.h -i
  sed 's/CHROME_INSTALLER/COMPONENTS/' *.cc *.h -i
  - Sorting works out pretty well!
- Change all 'chrome/installer/zucchini' to 'components/zucchini'
  throughout other parts of the repo; sort if necessary.
- Fix 6 'git cl lint' errors.
- Change 1 Bind() usage to BindRepeated().
- Update OWNER.
