feat: add importTime to the accounts controller metadata

[owencraston]

On mobile we are relying on the import time of an account to perform certain U.I logic. This is data we are getting from the the metadata within the identities object of the preferences controller.

Example

Preferences controller identities

{
  "0x4A29682b2636147F608CF7554F47bd9877117bDd": {
    "address": "0x4A29682b2636147F608CF7554F47bd9877117bDd",
    "name": "Account 1",
    "importTime": 1712527955387
  },
  "0x769ddE14f7D7D48eD431d727801620F46d7aE29e": {
    "address": "0x769ddE14f7D7D48eD431d727801620F46d7aE29e",
    "name": "Account 2",
    "importTime": 1712528157517
  },
  "0x9351164ED35aCe26F345F749B9Cb85b5C699E2b7": {
    "address": "0x9351164ED35aCe26F345F749B9Cb85b5C699E2b7",
    "name": "Account 3",
    "importTime": 1712528160433
  }

      }
    }
  },
  "selectedAccount": "04cc2134-f9f6-4a42-b07b-3ebc40078f4f"
}

In order to completely migrate all accounts data we will need this data.
