80262f0602 HV: rename append_seed_arg to fill_seed_arg
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.

47d20f37e1 HV: replace merge_cmdline api with strncat_s
Add a standard string api strncat_s() to replace merge_cmdline() to make code
more readable.

Another change is that the multiboot cmdline will be appended to the end of
configured SOS bootargs instead of the beginning, this would enable a feature
that some kernel cmdline paramter items could be overriden by multiboot cmdline
since the later one would win if same parameters configured in kernel cmdline.
