KVM: VMX: Disallow using to_vmx() in common VT code

Poison to_vmx() in main.c and posted_intr.c so that attempting to interpret
the vCPU as a VMX vCPU will fail at compile time, as opposed to failing at
runtime, or worse corrupting state without outright failing.

Note, to_tdx() is buried in tdx.c, i.e. isn't broadly reachable, and so
doesn't need the same treatment as to_vmx().
