For service and pre-launched VMs, the image loaders in ACRN
are functioning the same way as an in-guest bootloader such
as GRUB, which allows ACRN to load a guest image and start
directly from there and therefore skipping the firmware
initialization stage.

To re-use image loader code as much as possible, the image loader
logic is splitted into two stages, the loading stage and
environmental preparation stage. Most part of the loading stage
are common logic, and environmental preparation stage should
be completely arch-specific.

The best place for stage two loader logic is arch_vm_prepare_bsp,
which prepares vcpu register states based on the loaded image
(entry point, load address, etc.).

This commit refactors only the rawimage loader. Other loaders
are left for future improvement.
