ReceiveChannel.asFlow operator

See original GitHub issue

A missing piece of the Flow puzzle is a connection between regular ReceiveChannel and Flow (note that we already have a pretty non-obvious ReceieveChannel.asFlux) with a proper migration path for channel operators.

For example, all operators on top of the channels are deprecated, but users have no clear migration path from their channel operators sequence to flow.

The main focus here is to provide clear consumption semantics and decide whether we want to introduce such primitive at all

The proposal is to name it consumeAsFlow and add additional precaution that repeated attempts to collect from the resulting flow produce IllegalStateException just in case. See https://github.com/Kotlin/kotlinx.coroutines/blob/bc34a2e0d136d3635f6413c0e7885cf7f527f857/kotlinx-coroutines-core/common/src/flow/Channels.kt#L17-L29

You are right, @elizarov, I confused this use case with the example https://github.com/Kotlin/kotlinx.coroutines/issues/1326#issuecomment-509144702 , in that case asFlow drops messages (and so on… see other issue).
