refactor(core): export additional methods from primitives/signals (#56759)

Browse source 
Export `producerIncrementEpoch` which was missing before, as well as a new
`runPostSignalSetFn` helper. These changes make it easier to write `signal`-
like utilities which don't use the `createSignal` abstraction.
