Hi internals,

I'm looking for feedback on a small pdo_sqlite addition.

PR: https://github.com/php/php-src/pull/21456
Implements: https://github.com/php/php-src/issues/21322

Two new read-only statement attributes on Pdo\Sqlite:
- Pdo\Sqlite::ATTR_SQL — original SQL text of a prepared statement (via
sqlite3_sql())
- Pdo\Sqlite::ATTR_EXPANDED_SQL — SQL with bound parameters inlined (via
sqlite3_expanded_sql())

$stmt = $db->prepare('SELECT :name AS greeting');
$stmt->bindValue(':name', 'hello');
$stmt->execute();

$stmt->getAttribute(Pdo\Sqlite::ATTR_SQL);          // "SELECT :name AS
greeting"
$stmt->getAttribute(Pdo\Sqlite::ATTR_EXPANDED_SQL); // "SELECT 'hello' AS
greeting"

This mirrors SQLite3Stmt::getSQL() from the non-PDO API, but uses PDO's
getAttribute() mechanism rather than adding a driver-specific method. The
attribute system is how PDO drivers expose driver-specific functionality,
so it's a natural fit.

ATTR_EXPANDED_SQL is gated behind a configure check for
sqlite3_expanded_sql availability.

I don't think this needs a full RFC given the scope (two read-only
attributes, single driver, no BC impact), but I wanted input from the list.

Thoughts?
