A security fix will need those functions, so back-patch the v14+ functions to v13. When commit b80e10638e36b9d2f0b39170c613837af2ca2aac introduced the v14+ implementation of pg_encoding_verifymbstr(), it added a callback to each pg_wchar_table entry. For simplicity and ABI stability, this instead implements the function in terms of the existing per-character callback.
