[GN] Fix "gn gen --ide=vs" to ignore bundle_data targets.

In order to keep the BUILD.gn more readable by avoiding conditionals,
Chromium defines bundle_data on every platforms (as in the absence of
create_bundle they are just no-op stamp targets).

Fix "gn gen --ide=vs" to ignore bundle_data targets but not the
create_bundle targets (as there should be no such targets on Windows).
