[chain] move gnoland start's genesis generation to cmd/genesis

Master issue: #1836;
From this issue comment: #1836 (comment)

At the moment, the gno.land node uses the generateGenesisFile function to set up the genesis file, including transactions, genesis balances and also the packages and realms in the examples/ directory.

Ideally, this step of genesis generation should be delegated to the genesis command; so that gnoland start only ever has to concern itself with starting the node proper. The long-term vision is that the Gno.land node should be able to run without needing a "root directory" (ie. being placed in the monorepo's directory structure).

Proposed DoD

• Create genesis packages, with subcommands to:
  • list all addpkg transactions (what packages will be created at genesis)
  • get an addpkg transaction, filtering by pkgpath, showing the contents as well.
  • del an addpkg transaction, filteriing by pkgpath.
  • add to add a directory containing packages (ie. gnoland add examples or gnoland add examples/gno.land/p/demo/avl)
    • NOTE: this should place packages taking care to load them in their "dependency order" using gno.mod; ie. what generateGenesisFile is doing right now.
  • clear to remove all addpkg transactions.
• Move the default genesis transactions and balances files to a default.genesis.json
  • Balances can already be easily manipulated using genesis balances, so they don't need to have separate files
• Create a makefile recipe to easily set up a genesis.json, combining default.genesis.json with genesis clear; genesis add ../examples.

@zivkovicmilos Question: do we plan a gnoland init command? (combining config init + secrets init?). If so, should genesis clear; genesis add ../examples be a part of it?

Most def: #1885

I see no reason why not, since gnoland init will just be the default initialization ✅

@harry-hov what's the status for this issue? #1988 is related but doesn't resolve this one.

[harry-hov]

@Kouteki #1988 is the first step in the direction of solving this issue. Further work will be done on top of it.

@Kouteki
We have finished the scope of this task that we needed for test4, the leftover scope is left over for a subsequent rolling release

I've moved the milestone to post launch
