define block hash provider and default impl using frame_system (#4080) · 5b513cc0

Vedhavyas Singareddi authored Apr 13, 2024

This PR introduces `BlockHashProvider` into `pallet_mmr::Config`
This type is used to get `block_hash` for a given `block_number` rather
than directly using `frame_system::Pallet::block_hash`

The `DefaultBlockHashProvider` uses `frame_system::Pallet::block_hash`
to get the `block_hash`

Closes: #4062
