Adds an IGVM loader to QEMU which processes a given IGVM file and
applies the directives within the file to the current guest
configuration.
The IGVM loader can be used to configure both confidential and
non-confidential guests. For confidential guests, the
ConfidentialGuestSupport object for the system is used to encrypt
memory, apply the initial CPU state and perform other confidential guest
operations.
The loader is configured via a new IgvmCfg QOM object which allows the
user to provide a path to the IGVM file to process.
