Make PutStoredScriptRequest immutable (#117556)

No need for this request to be mutable, we always know all the values at
creation time. Also adjusts the `toString()` impl to use the `source`
field, since this is the only spot that we use the `content` so with
this change we can follow up with a 9.x-only change to remove it.
