rust: module_param: return value by copy from value

Browse source

For `Copy` parameter types it is more ergonomic to retrieve the
parameter value by copy than through a shared reference. Change
`ModuleParamAccess::value` to return `T` by copy when `T: Copy`,
and rename the previous reference-returning accessor to
`value_ref`. Update the in-tree caller in `rust_minimal`.
