Initialize the IDT and exception handlers for all non-barebones VMs and
vCPUs on x86. Forcing tests to manually configure the IDT just to save
8KiB of memory is a terrible tradeoff, and also leads to weird tests
(multiple tests have deliberately relied on shutdown to indicate success),
and hard-to-debug failures, e.g. instead of a precise unexpected exception
failure, tests see only shutdown.

Now that kvm_vm_arch exists, move the GDT, IDT, and TSS fields to x86's
implementation, as the structures are firmly x86-only.

Make TEST_ASSERT_KVM_EXIT_REASON() macro and replace all exit reason
test assert statements with it.
No functional changes intended.
