Emit error when Config part is imported but without the std feature (#9225)

* Emit error when Config part is imported but without the std feature

* Add UI test for missing std feature on GenesisConfig

* Update frame/support/test/Cargo.toml

Co-authored-by: Guillaume Thiolliere <gui.thiolliere@gmail.com>

* Remove unused imports

* Unify all dummy party checker macros

* Fix

* Dispaly pallet_path::GenesisConfig instead of PalletConfig in error message

* Revert changes to construct_runtime_ui.rs

* Add additional parameter for dummy part checker macro

* Apply suggestions from code review

* fix master merge: update version

* update Cargo.lock
