KVM: selftests: Add all (known) EFLAGS bit definitions
Add #defines for all known EFLAGS bit, e.g. so that tests can use things
like EFLAGS.TF to validate single-stepping behavior. Opportunistically
use X86_EFLAGS_FIXED instead of an open-coded equivalent when stuffing
initial vCPU state.
No functional change intended.
