Cannot create TDX-enabled image with packer

[gilbahat]

Description

Please enable the TDX compute type option when creating an image. without this option, only AMD-SEV virtualization is supported.

when using gcloud, there is a dedicated switch, --confidential-compute-type=TDX (the default is SEV)

Use Case(s)

TDX is an alternative technology to AMD SEV which may be preferred by the image creator/maintainer

Potential configuration

confidential_compute_type = TDX / SEV
