Richard Newman e33fe71c47 Rework caching and use it inside the query engine. (#553) r=emily 
This puts caching in mentat_db, adds a reverse lookup capability for
unique attributes, and populates bidirectional caches with a single
SQL cursor walk.

Differentiate between begin_read and begin_uncached_read.

Note that we still allow toggling within InProgress, because there might be
transient local state that makes starting a new transaction impossible.

This crate turns an algebrized Datalog query into a domain-specific representation of a SQL query, and then uses mentat_sql to turn that into a SQL string to be executed.

This subsumes both planning and query construction, because in Mentat the SQL query is effectively a query plan.
