Initialize and sanitize a acrn specific multiboot info struct with current
supported multiboot1 in very early boot stage, which would bring below
benifits:
- don't need to do hpa2hva convention every time when refering boot_regs;
- panic early if failed to sanitize multiboot info, so that don't need to
check multiboot info pointer/flags and panic in later boot process;
- keep most code unchanged when introduce multiboot2 support in future;

We hit build issue if the ld version is 2.34:
error: PHDR segment not covered by LOAD segment
One issue was created to binutils bugzilla system:
https://sourceware.org/bugzilla/show_bug.cgi?id=25585
From the ld guys comment, this is not an issue of 2.34. It's an
issue fixing of the old ld. He suggested to add option
--no-dynamic-linker
to ld if we don't depend on dynamically linker to loader our binary.

BVT (Borrowed virtual time) scheduler is used to schedule vCPUs on pCPU.
It has the concept of virtual time, vCPU with earliset virtual time is
dispatched first.
Main concepts:
tick timer:
a period tick is used to measure the physcial time in units of MCU
(minimum charing unit).
runqueue:
thread in the runqueue is ordered by virtual time.
weight:
each thread receives a share of the pCPU in proportion to its
weight.
context switch allowance:
the physcial time by which the current thread is allowed to advance
beyond the next runnable thread.
warp:
a thread with warp enabled will have a change to minus a value (Wi)
from virtual time to achieve higher priority.
virtual time:
AVT: actual virtual time, advance in proportional to weight.
EVT: effective virtual time.
EVT <- AVT - ( warp ? Wi : 0 )
SVT: scheduler virtual time, the minimum AVT in the runqueue.
