performance-metrics: Add vm_type param to new_guest

Browse Source 
Update performance_test_new_guest() to accept a GuestVmType
parameter. When set to Confidential, configure the guest with
CVM-specific settings: vm_type, boot_timeout, and nested
virtualization disabled.

All callers pass GuestVmType::Regular to preserve existing
behavior.
