riscv: cpufeature: Fix Zk bundled extension missing Zknh

The Zk extension is a bundle consisting of Zkn, Zkr, and Zkt. The Zkn
extension itself is a bundle consisting of Zbkb, Zbkc, Zbkx, Zknd, Zkne,
and Zknh.

The current implementation of riscv_zk_bundled_exts manually listed
the dependencies but missed RISCV_ISA_EXT_ZKNH.

Fix this by introducing a RISCV_ISA_EXT_ZKN macro that lists the Zkn
components and using it in both riscv_zk_bundled_exts and
riscv_zkn_bundled_exts.

This adds the missing Zknh extension to Zk and reduces code duplication.
