Subject: [PATCH] Enable SQLite column metadata

Build Unix SQLite with SQLITE_ENABLE_COLUMN_METADATA so the metadata APIs are available on macOS and Linux.

Remove the pdo_sqlite configure override that forced PHP to treat sqlite3_column_table_name() as unavailable, and add sanity checks for both SQLite compile options and PDO column metadata.
