Introduce Kunit tests for fs/ext4/hash.c to verify ext4fs_dirhash() across the legacy, half-MD4, and TEA hash variants. The tests cover empty, seeded hashing, and non-ASCII name handling. They also verify error paths, including invalid hash versions and SipHash without a configured key, and check that the signed and unsigned hash variants differ on non-ASCII input as expected. When CONFIG_UNICODE is enabled, the tests further verify casefolded-name hashing and the fallback behavior for invalid input.
