Matter add internal debug option

[s-hadinger]

Description:

Matter add "debug":true option to log all values read when a wildcard read request is received. They are normally not logged for performance reason, but useful when developing. This option is JSON only and not available in UI because we don't want users to activate it without knowing the performance impact.
