backends/igvm: Process initialization sections in IGVM file
The initialization sections in IGVM files contain configuration that should be applied to the guest platform before it is started. This includes guest policy and other information that can affect the security level and the startup measurement of a guest. This commit introduces handling of the initialization sections during processing of the IGVM file. Signed-off-by: Roy Hopkins <roy.hopkins@randomman.co.uk> Acked-by: Michael S.
