Reviewed by Kentaro Hara.

Fix the JS bindings generator so that it stops including JS*Custom.h header whenever
[CustomPutFunction] or [CustomNamedSetter] IDL extended attributes are used. We don't
really need this custom header and this forces the developer to create dummy custom
headers so that it builds.

If the developer really needs such custom header to be included, he can still use
[JSCustomHeader] IDL extended attribute to do so.

This patch also remove the dummy custom headers that were created but are no longer
required to build.

No new tests, no behavior change. Already covered by the following bindings test:
