Add hwprobe test for Zicboz and its block size. Also, when Zicboz is present, test that cbo.zero may be issued and works. Additionally provide a command line option that enables testing that the Zicbom instructions cause SIGILL and also that cbo.zero causes SIGILL when Zicboz it's not present. The SIGILL tests require "opt-in" with a command line option because the RISC-V ISA does not require unimplemented standard opcodes to issue illegal-instruction exceptions (but hopefully most platforms do). Pinning the test to a subset of cpus with taskset will also restrict the hwprobe calls to that set.
