Publish Z3 symbols (#6280)

* WiP: publish symbols for package

* set debugtype to full

* fix internal nuget feed publishing

* Try pipeline github authorization

* Update github service connection

* WiP: try symbol publish in build

* try Z3Prover for GitHub connection

* WiP: collect symbols

* revert symbol type to pdbonly (only portable is not supported for publishing)

* Publish symbols in nightly and release

* Revert this: comment out publish to test release build pipe

* restore publishing

* Turn of index sources to eliminate warning that it is not supported for Github
