gh-153695: Fix sqlite3.Row.__hash__ with an unhashable value

[tonghuaroot]

sqlite3.Row.__hash__ did not check the -1 error return of PyObject_Hash,
so hashing a row that holds an unhashable value raised SystemError instead of
TypeError. Check each hash and propagate the exception.

• Issue: sqlite3.Row.__hash__ raises SystemError instead of TypeError for an unhashable value #153695

Done, the 3.13 backport is #153725. miss-islington hit a conflict because 3.13 still has the older pysqlite_row_hash(pysqlite_Row *self) signature, so I resolved it by hand; the fix itself is identical. Thanks for merging!
