Allow to log raw parse tree.
This commit allows to log the raw parse tree in the same way we
currently log the parse tree, rewritten tree, and plan tree.
To avoid unnecessary log noise for users not interested in this
detail, a new GUC option, "debug_print_raw_parse", has been added.
When starting the PostgreSQL process with "-d N", and N is 3 or higher,
debug_print_raw_parse is enabled automatically, alongside
debug_print_parse.

prion is complaining here:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=prion&dt=2025-09-05%2023%3A03%3A05
I did not look into the details, but this usually points to a
use-after-free problem.
