Create third custody option for wallet data: semi-custodial

[corwintines]

Is your feature request related to a problem? Please describe.

• Currently, the data gathered for wallets for custody is binary (custodial, non-custodial). The decision for custody is made on whether you own your keys and have custody over your account or not. However, there is a third option that should be added, semi-custodial. MPC wallets as an example, use (potentially) centralized servers to store part of the secrets to your account, but not all of them as you have custody over your portion of the secrets. All these secrets are needed to produce the private key for a transaction, but no party has all the secrets, distributing the security.

Describe the solution you'd like

• Have custody be a ternary enum (custodial, semi-custodial, non-custodial) instead of binary (custodial, non-custodial).

Closing this out at the moment. Would like to refresh this issue to account for Account abstraction and smart contract accounts given the development over the past 2 years.
