We can extends RISC-V hwprobe support to include `RISCV_HWPROBE_KEY_ZICBOZ_BLOCK_SIZE`.
The probed value is recorded in VM_Version::zicboz_block_size and then used to set zicboz_block_size.
This ensures correct usage of the Zicboz extension, as block zeroing instructions operate on cache-line granularity.
