localbuf: Introduce FlushLocalBuffer()

Browse Source 
Previously we had two paths implementing writing out temporary table
buffers. For shared buffers, the logic for that is centralized in
FlushBuffer(). Introduce FlushLocalBuffer() to do the same for local buffers.

Besides being a nice cleanup on its own, it also makes an upcoming change
slightly easier.
