crypto: pcbc - Remove support for PCBC mode

The only user of PCBC mode (Propagating Cipher Block Chaining mode) was net/rxrpc/rxkad.c, which now uses local code instead. While PCBC was an interesting cryptographic experiment, it has largely been relegated to the history books and academic exercises. It is non-parallelizable (i.e., very slow) and doesn't actually achieve the integrity properties it was apparently intended to achieve. Remove support for it from the crypto API.
