Description
Wire the FTS / inverted build to write posting-list segments to SpillStore (#7300) when the MemoryPool signals pressure (#7301). Add a codec for (de)serializing posting segments to scratch.
Part of #7302.

Research direction
Start by tracing the FTS/inverted build, SpillStore, and MemoryPool pressure signal described in #7300 and #7301. Identify the existing scratch-storage interfaces and posting-segment representation before adding the requested serialization path; done means posting-list segments spill through SpillStore when pressure is signaled.
