[FLINK-7746][network] move ResultPartitionWriter#writeBufferToAllChannels
implementation up into ResultPartition
## What is the purpose of the change
As a step towards removing the (unneeded) `ResultPartitionWriter` wrapper,
we should move `ResultPartitionWriter#writeBufferToAllChannels` into
`ResultPartition` where single-channel writing happens anyway.
## Brief change log
- move the implementation of
`ResultPartitionWriter#writeBufferToAllChannels` into `ResultPartition` (keep a
delegating method for now - until `ResultPartitionWriter` is removed)
## Verifying this change
This change is a trivial rework / code cleanup without any (new) test
coverage.
