Improve trusted-suppress-native-method scriptlet

Browse source 
Add `debug` as disposition option: if the `how` parameter is `debug`,
the scriptlet will trigger a `debugger` statement and the target
method won't be suppressed. Useful to find out how the method is
being called by page code. To be used for investigation purpose only.
