Fix #64937: Firebird PDO preprocessing sql
This patch fixes some problems with preprocessing SQL queries.
* The new algorithm takes into account single-line and multi-line
comments and ignores the ":" and "?" Parameter markers in them.
* The algorithm allows the EXECUTE BLOCK statement to be processed
correctly. For this statement, it is necessary to search for
parameter markers between EXECUTE BLOCK and AS, the rest should be
left as is.
The SQL preprocessing code has been ported from Firebird to handle
EXECUTE STATEMENT.
Closes GH-4920.
