backends/igvm: Add IGVM loader and configuration
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.
