Series t/unit-tests: convert hash tests to use clar | expand

Commit Message

Seyi Kuforiji Jan. 7, 2025, 9:19 a.m. UTC 
Adapt the hash test functions to clar framework by using clar
assertions where necessary. Following the consensus to convert
the unit-tests scripts found in the t/unit-tests folder to clar driven by
Patrick Steinhardt. Test functions are structured as a standalone to
test individual hash string and literal case.
