frame: Enable GenesisConfig in no_std (#14108)

* frame: Default for GenesisConfig in no_std

`Default` for `GenesisConfig` will be required for no_std in no native
runtime world. It must be possible to instantiate default GenesisConfig
for pallets and runtime.

* ".git/.scripts/commands/fmt/fmt.sh"

* hash69 in no_std reverted

* derive(DefaultNoBound) for GenesisConfig used when possible

* treasury: derive(Default)

* Cargo.lock update

* genesis_config: compiler error improved

When std feature is not enabled for pallet, the GenesisConfig will be
defined, but serde::{Serialize,Deserialize} traits will not be
implemented.

The compiler error indicates the reason of latter errors.

This is temporary and serde traits will be enabled with together with
`serde` support in frame.
