Removes custom established VPs

[grarco]

Describe your changes

Closes #2554.

Modifies tx_init_account and tx_update account to not write the vp key. Updates of it are not supported for now and when initializing a new established account (also for validators) the protocol automatically assigns it the vp_user.

The host function update_validity_predicate has been removed.

The accounts' vps have been removed from the genesis files.

@cwgoes do we really want to remove the possibility to update vps via governance? can't we just remove the possibility for usersd to update their acccou t vp and have just the default one? vps are whitelisted anyway and if we just remove the possibility from CLI and wasm transaction to update the validity predicate we can retain the possibility to create multiple of them via governance.

Yeah - I think we can retain the possibility to update VPs via governance, I just want to remove the user-submitted txs.

After #2770 we probably need to rethink this a bit since we might need to let user update their vps

[grarco]

About my previous comment: given the way we chose to remove vps from the allowlist, I believe we need to revert the tx_update_account tx to allow the update of the vp in case it was removed from the allowlist. We can still prevent custom vps in genesis instead

is this something we still want to include in the near future?
