Switch remaining stamp targets to phony targets

GN uses stamp files for a variety of output types as a mechanism for
completing a group of dependencies. Ninja's phony targets can be used in
a similar manner.

The GN 'group', 'generated_file', 'bundle_data', 'copy', 'action',
'action_for_each' and 'create_bundle' output types each generate a stamp
file as an output for other targets to depend on. This CL replaces those
stamp targets with a phony alias target.

For a few target types, GN optionally creates a "<target>.inputdeps"
and/or "<target>.input" stamp files to represent a group of input
dependencies or inputs, respectively. This is useful for limiting the
size of ninja files because the dependencies only have to be listed
once. As with the stamp files generated for the aforementioned output
types, this CL also replaces those stamp targets with a phony alias
target.

Finally, there are several intermediate stamp files that are created for
certain outputs, such as the code signing stamp for `create_bundle`
targets. Where possible, these are also replaced with phony alias
targets.
