Set injectDebuggingSupportCode in DWDS based on specified device ID (flutter#165820)

This change ensures that `injectDebuggingSupportCode` in DWDS is set
based on the specified device ID, defaulting to Chrome. This complements
the changes made in dart-lang/webdev#2601 and
ensures that debugging support is correctly configured for different
environments.

fixes dart-lang/sdk#60289
