vmm: Make kernel optional in VM internals

Browse Source 
When booting with TDX no kernel is supplied as the TDFV is responsible
for loading the OS. The requirement to have the kernel is still
currently enforced at the validation entry point; this change merely
changes function prototypes and stored state to use Option<> to support.
