x86/srso: Disentangle rethunk-dependent options
CONFIG_RETHUNK, CONFIG_CPU_UNRET_ENTRY and CONFIG_CPU_SRSO are all
tangled up. De-spaghettify the code a bit.
Some of the rethunk-related code has been shuffled around within the
'.text..__x86.return_thunk' section, but otherwise there are no
functional changes. srso_alias_untrain_ret() and srso_alias_safe_ret()
((which are very address-sensitive) haven't moved.
