When debugging the HV, we may want to check the HV version information
frequently. In current HV shell command, there is no such kind of command
to check this information. We can only scroll up the HV console log to
get the information. If there are very huge amount of lines of log, it
will be very time-wasting to get the HV version information.
So, this patch adds 'version' command to get the HV version information
conveniently.

In previous code, only for pre-launched VM, hypervisor would create
vuart console for each VM. But for post-launched VM, no vuart is
created.
In this patch, create vuart according to configuration in structure
acrn_vm_config. As the new configuration is set for pre-launched VM and
post-launched VM, and the vuart initialize process is common for each
VM, so, remove CONFIG_PARTITION_MODE from vuart related code.

strncpy_s(d, dmax, s, slen): the 'dmax' includes the null terminator, while
slen doesn't. Thus if (dmax == slen == strlen(s)), strncpy_s() chooses to
discard the last character from s and instead write '\0' to d[dmax - 1].
strnlen_s(s, maxsize): if there is no terminating null character in the
first maxsize characters pointed to by s, strnlen_s() returns maxsize.
So in the following example or similar cases, we need to increase the size
of d[] by 1 to accommodate the null terminator, and add '1' to the dmax
argument to strncpy_s().
uint8_t d[MAX_LEN];
size = strnlen_s(s, MAX_LEN);
strncpy_s(d, MAX_LEN, s, size);
