[12.x] Adds a new method "getRawSql" (with embedded bindings) to the QueryException class

[erickcomp]

Description

This PR adds a getRawSql to the QueryExceptionClass.

When error reporting/showing tools want to show "compiled" SQL (with embedded bindings), they resort to simple string substitution (which does not covers all cases), using something like Str::replaceArray('?', $bindings, $sql)

This newly introduce getRawSql methods uses the proper grammar of the connection in which the error occurred in order to generate the raw SQL, just like the query builder does.

Usage

->withExceptions(function (Exceptions $exceptions) {
    $exceptions->report(function (QueryException $e) {
        // ...
       MyErrorServiceFacade::report('Error executing SQL: ', $e->getRawSql());
    });
})

This allows one to send the problematic SQL with context, without having to send SQL and bindings separately or even resort to simple string substitution
