Replace .mojom.h includes with .mojom-forward.h in //chrome/browser (4/n)

This CL replaces .mojom.h includes with .mojom-forward.h in some
sub-directories of chrome/browser to reduce the pre-processed size
of header files and shorter build time. The sub-directories are following,

  - chrome/browser/ssl
  - chrome/browser/storage
  - chrome/browser/sync
  - chrome/browser/task_manager

This CL has no behavior changes.
