Tool support: add two new options to the jmod and jar tools to populate the fields of the ModuleResolution attribute.

 1) The `--warn-if-resolved` option which takes exactly one of three possible arguments: `deprecated`, `deprecated-for-removal`, or `incubating`.

 2) The '--do-not-resolve-by-default` option, which takes no argument.

These options are mentioned in the incubator module JEP [1] and will be documented in JEP 261 [2]. They are omitted from `--help` output, as they are not of broad interest.

As per JEP 11 [1], at link and run time an unsuppressible warning will be emitted if a module that has `--warn-if-resolved=incubating` is resolved. At run time, modules that are `do-not-resolve-by-default` will be omitted from the initial set of root modules and subsequent service binding, unless explicitly added by the `--add-modules` command line option, or an explicit `requires` clause.
