* [NXP] Improve DnssdImplBr to handle a list of queries instead of a single instance

This commit adds support for handling multiple queries at the same time.
For example, if the device is trying to do multiple CASE sessions at once,
each of them will trigger a node resolve. The new implementation uses
lists for handling resolve or browse operations at the same time.
Also, the list allows determining if a query is in progress and let mDNS
module handle it according to specification. This means that we will not
restart the query but allow the normal resolve/browse operation to
continue as defined in the mDNS specification.
