Merkle Mountain Range pallet (#7312)

* Add MMR pallet. * WiP * Working on testing. * WiP - test * Tests passing. * Add proof generation. * Generate and verify proofs. * Allow verification of older proofs. * Move stuff to a module. * Split MMR stuff to it's own module. * Add docs. * Make parent hash optional. * LeafData failed approach. * Finally implement Compact stuff. * Compact encoding WiP * Implement remaining pieces. * Fix tests * Add docs to compact. * Implement for tuples. * Fix documentation. * Fix warnings and address review suggestion. * Update frame/merkle-mountain-range/src/primitives.rs Co-authored-by: cheme <emericchevalier.pro@gmail.com> * Address review grumbles. * Removing missing crate. * Fix test. * Add some docs and test. * Add multiple instances. * Cargo.toml sync. * Fix no_std compilation. * More no_std stuff. * Rename MMR struct. * Addressing other grumbles. * Fix test. * Remove format for no_std compat. * Add test for MMR pallet. * Fix std feature. * Update versions. * Add to node/runtime. * Add hook to insert digest. * Make primitives public. * Update lib.rs tech spec/typos etc * Use WeightInfo and benchmarks. * Fix test. * Fix benchmarks. * Trait -> Config. * Fix typo. * Fix tests.
