BCF 2440 remove chainsets from core (#10349)

* add native token field to cosmos config

* remove fcdurl

* change gas token to native token

* rename to fee token

* add basic methods to chain service

* add bech32 prefix to cosmos config

* bump chainlink-cosmos to feature branch

* fix type error

* update chain-cosmos.toml

* fix fee estimator test

* fix types and gas price estimator input

* make config-docs

* update chainlink-cosmos version

* fix cosmos config tests

* update tomls and types

* GetChainStatus, ListNodeStatuses for cosmos and evm

* fix tests

* cleanup CosmosSendAtom

* solana and starknet. fix solana tests

* fix docs and scripts tests

* remove atom references

* use ValidateDenom

* fix cosmos config in relayer test

* sort cosmos config fields alphabetically

* undo accidental test changes

* WIP: remove chainset implementation from all chains

* bump chainlink-cosmos version

* fix cosmos config order

* update relay factor to work with chains instead of chainsets

* remove chainsets implementations :)

* fix implementations to work with existing loop.Relay interfaces. previous developed in a workspace with modified interfaces

* fix dependencies

* fix nil test failure and linter

* fixes and more tests

* update toml passed to loop

* address comments; fix or document TODOs; revert test changes; move/rename code for clarity

* fix variable naming and error messages and revert total to -1 on error
