Post-migration follow ups (VM v0.20.1): tracking issue

[Fumuran]

After the #2158 will be merged, we should address the remaining issues:

• Remove the SMT_PEEK_EVENT from asset vault: Remove the SMT_PEEK_EVENT event #2115.
• Change hperm and hmerge to rpo256::permute and rpo256::merge everywhere.
• Rename RpoFalcon512 to Falcon512Rpo everywhere.
• Figure out if we can still search for procedures by name in account components: Search account component procedure by name #2185
• Export/import constants directly (instead of having wrapper functions): Import constants directly instead of through procedures #2168
