A value in empty windows expands to no values, so it can be dropped at
any time, perhaps unintentionally. This has bitten runner authors, including
Spark & Dataflow.
While creating such a thing in memory is not automatically problematic, it
is also not really useful. So this change removes it.

> Key: BEAM-191
> URL: https://issues.apache.org/jira/browse/BEAM-191
> Project: Beam
> Issue Type: Bug
> Components: sdk-java-core
> Reporter: Kenneth Knowles
> Assignee: Kenneth Knowles
> Priority: Minor
> Labels: windowing
>
> Even though it is acceptable to create a WindowedValue carrying no windows
> when it is a fully reified WindowedValue<T>, it doesn't really make sense:
> When it becomes an element in a PCollection that a value must exist within
> some window.
> This has led to some confusion so we should remove the API. It seems there
> are just 11 files that reference WindowedValue.valueInEmptyWindows [1] that
> mostly look like they'd be fine with the global window.
