HV: use tag to specify multiboot module

Browse Source 
Previously multiboot mods[0] is designed for kernel module for all
pre-launched VMs including SOS VM, and mods[0].mm_string is used
to store kernel cmdline. This design could not satisfy the requirement
of hybrid mode scenarios that each VM might use their own kernel image
also ramdisk image. To resolve this problem, we will use a tag in
mods mm_string field to specify the module type. If the tag could
be matched with os_config of VM configurations, the corresponding
module would be loaded;

Tracked-On: #3214
