cc @0xpatrickdev

stretch:

• add PSM

subsume mintHolder

idea: one interchainMints contract instead of N mintHolder contracts. privateArgs includes bankManager and nameAdmins for agoricNames.brand, agoricNames.issuer. creatorFacet includes makeInterchainAsset that

• creates an IssuerKit
• adds it to bankManager
• adds it to agoricNames.brand, agoricNames.issuer
