x86/nospec: Introduce CONFIG_SPECULATIVE_HARDEN_BRANCH
Just as with CONFIG_SPECULATIVE_HARDEN_ARRAY, branch hardening should be
configurable at compile time.
The previous CONFIG_HVM was a consequence of what could be discussed publicly
at the time the patches were submitted, and wasn't actually correct. Later
patches will make further corrections.
