Description

currently, the group_imports option only accepts Preserve and StdExternalCrate. If I want a new order like StdCrateExternal, it need to PR the rustfmt, make it supports this order

consider the group_imports can accept a new value type: string array, like: ["Std", "External", "Crate"], it will allow users custom their project import order, like ["Std", "Crate", "External"]

Research direction

Start by locating the implementation and tests for the group_imports option and reviewing how its current Preserve and StdExternalCrate values are handled. Define the supported custom ordering and configuration behavior, then verify that the requested order works without breaking the existing values.
