ext/pdo_odbc builds the result string from the driver-reported fetched_len, which on truncation exceeds the bound colsize+1 buffer (SQL_SUCCESS_WITH_INFO), over-reading heap into the returned value. Clamps to the bound capacity for short-bound columns only, so long columns are unaffected. Reproduces with the SQLite3 ODBC driver; the test skips without it. Sibling of GH-22668.

Fixes #22667
