x86/its: Add support for RSB stuffing mitigation
commit facd226f7e0c8ca936ac114aba43cb3e8b94e41e upstream.
When retpoline mitigation is enabled for spectre-v2, enabling
call-depth-tracking and RSB stuffing also mitigates ITS. Add cmdline option
indirect_target_selection=stuff to allow enabling RSB stuffing mitigation.
When retpoline mitigation is not enabled, =stuff option is ignored, and
default mitigation for ITS is deployed.
