[ASTERIXDB-2488][COMP] Support aggregate window functions

- user model changes: yes

- storage format changes: no

- interface changes: no

Details:

- Implement aggregate window functions:

agg_func() OVER (frame_var AS)? (PARTITION BY ... ORDER BY ... frame_spec)

- Where agg_func is a SQL/SQL++ aggregate function

- Fix percent_rank() to always return 0 for the first tuple

- Fix ntile() to handle NULL argument

- Log query after each rewrite rule in SqlppQueryRewriter

- Implement toString() for ADayTimeDuration, fix it for AYearMonthDuration

- Add seek() method to RunFileReader

[ASTERIXDB-2441][COMP] Improve column alias handling in ORDERBY/LIMIT

- user model changes: no

- storage format changes: no

- interface changes: no

Details:

- Introduce LET clauses for column alias expressions

instead of inlining them into ORDER BY/LIMIT clauses

- Fix incorrect visitor used in SubstituteGroupbyExpressionWithVariableVisitor

for rewriting LET clauses after GROUP BY

[ASTERIXDB-2394][COMP] Align VarCounter in query rewritting

- user model changes: no

- storage format changes: no

- interface changes: no

Details:

Currently, before we do certain language rewritings, we take a snapshot

of the var counter in the context and pass it to the rewriter. This

works fine in most of the cases, but it can fail when the rewriter

introduces new variables. This will cause different variables map to the

same variable id. Although this error may be fixed by another

ScopingVisitor, the compiler could fail if there is no more visitor down

in the rewriting workflow.

- user model changes: yes

- storage format changes: no

- interface changes: no

Details:

- Improved name resolution rules

of its input operator when analyzing its expression

- Fix ExternalGroupByPOperator to use input schema of its

aggregate function when generating runtime for that function

- Fix invalid free variable computation for GroupBy clause
