Allow tupleslots to have a fixed tupledesc, use in executor nodes.
The reason for doing so is that it will allow expression evaluation to
optimize based on the underlying tupledesc. In particular it will
allow to JIT tuple deforming together with the expression itself.
For that expression initial

Do execGrouping.c via expression eval machinery, take two.
This has a performance benefit on own, although not hugely so. The
primary benefit is that it will allow for to JIT tuple deforming and
comparator invocations.
Large parts of this were previously committed (773aec7aa), but the

Fix crash when canceling parallel query
elog(FATAL) would end up calling PortalCleanup(), which would call
executor shutdown code, which could fail and crash, especially under
parallel query. This was introduced by

Remove some inappropriate #includes.
Other header files should never #include postgres.h (nor postgres_fe.h,

file to explicitly include elog.h or palloc.h, because postgres.h pulls
those in already.
