Source generated json serializers (#4582)
* Use source generated json serializers in order to improve code trimming

* Use strongly typed github releases model to fetch updates instead of raw Newtonsoft.Json parsing

* Use separate model for LogEventArgs serialization

* Make dynamic object formatter static. Fix string builder pooling.

* Do not inherit json version of LogEventArgs from EventArgs

* Fix extra space in object formatting

* Write log json directly to stream instead of using buffer writer

* Rebase fixes

* Rebase fixes

* Rebase fixes

* Enforce block-scoped namespaces in the solution. Convert style for existing code

* Apply suggestions from code review

* Rebase indent fix

* Fix indent

* Delete unnecessary json properties

* Use default json options in github api calls

* Indentation and spacing fixes

* Fix json serialization

* Fix missing JsonConverter for config enums

* Add double \n\n after the whole string, not inside join
