Add TDX_BUG_ON() macros (with varying numbers of arguments) to deduplicate
the myriad flows that do KVM_BUG_ON()/WARN_ON_ONCE() followed by a call to
pr_tdx_error().  In addition to reducing boilerplate copy+paste code, this
also helps ensure that KVM provides consistent handling of SEAMCALL errors.

Opportunistically convert a handful of bare WARN_ON_ONCE() paths to the
equivalent of KVM_BUG_ON(), i.e. have them terminate the VM.  If a SEAMCALL
error is fatal enough to WARN on, it's fatal enough to terminate the TD.
