HV: move MAX_CONFIG_NAME_SIZE to acrn_common.h

The vm_config in hypervisor restricted VM name size to
MAX_CONFIG_NAME_SIZE (32 bytes). When UOS is launched by DM, the vmname
is passed in as the last optional args, we hope to to copy it to vm_config
in the future. So the size of vmname in DM args should be restricted to
MAX_CONFIG_NAME_SIZE, too. Because MAX_CONFIG_NAME_SIZE will be used by DM,
we move it from vm_config.h to acrn_common.h
We also rename MAX_CONFIG_NAME_SIZE to MAX_VM_OS_NAME_LEN, because it will
be used by another components, should has a clear name.
