Implement `AssetSelector` component

[FrederikBolding]

We should implement a way to let the Snap select from the assets in MetaMask without exposing all of the token details to the Snap.

State
The selected asset should be reflected in state with an object containing:

• asset: CAIP19Identifier
• name: string
• ticker: string

Props

• addresses: CAIP10Address[]
• chainIds?: CAIP2ChainId[] (Alternative filtering option to passing addresses)
• selectedAsset?: CAIP19Address

Selectors available here for non-EVM assets:

Maybe it should be assetType for consistency with the naming used in CAIP-19 for tokens.

Blocked for now for EVM assets - discussions with Assets team for workarounds.

Considering whether to support non EVM only for now.
