[Telemetry API] Prevent Subscriptions with different options from overwriting each other (#7930)

* initial implementation

* cleaning up a bit

* adding the hash method back as we dont want gigantic keys

* adding a line

* added filtering to state generator, updated filters readme to fix error, more robust hash function

* removing unnecessary changes in wrong file

* adding a test to confirm each endpoint has a separate subscription based of filtering

* lint

* adding back in hints, accidentally removed

* remove some redundant code and convert sanitization method into a replacer function for stringify

* tweaking serialize replacer to handle arrays correctly, adding more determinative row addition check to test

* more focused selector for the table

* simplified the serialization method even further and added some more docs
