Add syntax for referencing docs in other rule families.

This CL implements a new `${link rule.attribute}` syntax which can be used to
reference the documentation of rules and attributes of other rule families. For
example, `${link cc_library.deps}` will generate a link to the documentation for
the `deps` attribute of the `cc_library` rule. Similarly, this syntax can also
be used to reference sections of static documentation, for example
`${link common-definitions.label-expansion}`.
