The latest KVM in Linux-6.4-rc5 has support for:
1) Enabling/disabling SBI extensions from KVM user-space
2) Zbb ISA extension support
3) Zicboz ISA extension support
4) Ssaia ISA extension support

This series adds corresponding changes in KVMTOOL to use the above
mentioned features for Guest/VM.

These patches can also be found in the riscv_sbi_zbb_zicboz_ssaia_v2
branch at: https://github.com/avpatel/kvmtool.git

Changes since v1:
 - Rebased on commit b17552ee6c9728c20c9d0bd037ef134277daaa40
 - Fixed compile error for KVMTOOL x86 by adding __DECLARE_FLEX_ARRAY()
   in include/linux/stddef.h
