x86/bugs: Restructure SRSO mitigation

Browse source

Restructure SRSO to use select/update/apply functions to create
consistent vulnerability handling.  Like with retbleed, the command line
options directly select mitigations which can later be modified.

While at it, remove a comment which doesn't apply anymore due to the
changed mitigation detection flow.
