Rename JoinAwareConditionExpr to WhereTerm
...
We transform all JOIN conditions into WHERE clause terms in the query
planner. The JoinAwareConditionExpr name tries to make that point, but I
think it makes things more confusing. Let's call it WhereTerm (suggested
by Jussi).

optimizer.rs: refactor to use new data structures and remove unnecessary stuff
...
We don't need `push_predicates()` because that never REALLY was a predicate
pushdown optimization -- it just pushed WHERE clause condition expressions
into the correct SourceOperator nodes in the tree.
Now that we don't have a SourceOperator tree anymore and we keep the conditions
in the WHERE clause instead, we don't need to "push" anything anymore. Leaves
room for ACTUAL predicate pushdown optimizations later :)
We also don't need any weird bitmask stuff anymore, and perhaps we never did,
to determine where conditions should be evaluated.

Merge 'feat(optimizer): eliminate between statement' from KaguraMilet
...
Rewrite `Y BETWEEN X AND Z` as `X <= Y AND Y <= Z`. And due to the
support of this optimization rule, limbo should now be able to execute
the `BETWEEN AND` statement.
