    [PR/target 102957] Allow Z*-ext extension with only 2 char.

    We was assume the Z* extension should be more than 2 char, so we put an
    assertion there, but it should just an error or warning rather than an
    assertion, however RISC-V has add `Zk` extension, which just 2 char, so
    actually, we should just allow that.
