Previously append_seed_arg() just do fill in seed arg to dest cmd buffer,
so rename the api name to fill_seed_arg().
Since fill_seed_arg() will be called in SOS VM path only, the param of
bool vm_is_sos is not needed and will be replaced by dest buffer size.
The seed_args[] which used by fill_seed_arg() is pre-defined as all-zero,
so memset() is not needed in fill_seed_arg(), buffer pointer check
and strncpy_s() are not needed also.

Previously sanitize_multiboot_info() was called after init_debug_pre() because
the debug message can only print after uart is initialized. On the other hand,
multiboot cmdline need to be parsed before init_debug_pre() because the cmdline
could override uart settings and make sure debug message printed successfully.
This cause multiboot info was parsed in two stages.
The patch revise the multiboot parse logic that split sanitize_multiboot_info()
api and use init_acrn_multiboot_info() api for the early stage. The most of
multiboot info will be initialized during this stage and no debug message need
to be printed. After uart is initialized, the sanitize_multiboot_info() would
do sanitize multiboot info and print needed debug messages.

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;

- moving multiboot related MACROs in cpu_primary.S to multiboot.h;

Host ACPI parsing is needed during initialization only, not in run time.
Hence we don't need to clear U flag for memory in reserved or ACPI type
E820 entries.
- move enable_smep() and enable_smap() to the end of init_pcpu_post(),
so stac()/clac() can be removed from any init code before this point.
- call init_seed() before init_pcpu_post(), and rmeove stac()/clac() from
init_seed().

- for all cases of referring guest bootargs size, replace MEM_2K with
CONFIG_MAX_BOOTARGS_SIZE for better readability.
- remove duplicated MAX_BOOTARGS_SIZE definition from vm_config.h.
Also fix one minor issue in general_sw_loader() which uses copy_to_gpa()
to copy a string. Since copy_to_gpa() makes use of memncpy_s() to do the
job, the size parameter should include the string null ternimator.
