Some guest debuggers use the value of CR3 to attribute a debug event to
a guest process. Providing CR3 in the debug info makes this
significantly faster than doing KVM_GET_SREGS every time, so add support
for that. Also extend the debug_regs selftest to cover this.

  KVM: x86: Add CR3 to guest debug info
  KVM: selftests: Use TEST_ASSERT_EQ() in debug_regs
  KVM: selftests: Verify CR3 in debug_regs
