Rework migration and on runtime upgrade logic execution

[dmitrylavrenov]

The main goal of this PR is to avoid running runtime upgrade execution for each pallet on each runtime upgrade. The idea is taken from substrate and polkadot-sdk approach to use an ability passing actual migration at the runtime itself.

There are introduced separate objects responsible for runtime upgrade logic that implement OnRuntimeUpgrade to be passed at humanode-runtime to Executive like:

/// Executive: handles dispatch to the various modules.
pub type Executive = frame_executive::Executive<
    Runtime,
    Block,
     frame_system::ChainContext<Runtime>,
     Runtime,
     AllPalletsWithSystem,
     (
         init_storage_version::InitStorageVersion<DummyPrecompilesCode, Runtime>,
         init_storage_version::InitStorageVersion<BalancedCurrencySwapBridgesInitializer, Runtime>,
     ),
 >;

Please explain the logic behind this change - in particular why alter all the pallets

We'd have to put this on hold for now, a I need to do more research on this and dig deeper to really conclude something propely; note there are no useless migrations, and, in principle, migrations are to be kept forever; unless there is a special certain cutoff date for them.

Got it. The PR is not about avoiding having useless migrations, but to make the migrations itself more flexible. We can always have it at runtime level to keep it forever but control all migrations in one place.

Btw, looking forward to doing more research on your side and discussing later. I just was inspired by the general logic of custom upgrades usage after researching substrate updates related to polkadot-v0.9.43.
