fix(debugger): Enable iOS inspector modules on creation

When the application is being debugged with `--debug-brk --bundle`
options, the JS implementation objects handling the debugging protocol
are created after their corresponding domains' `enable` methods have
been called by the debugger frontend. As a workaround we now manually
call `enable` in their constructors.
