char: get rid of CharDriver

qemu_chr_new_from_opts() is modified to not need CharDriver backend[]
array, but uses instead objectified qmp_query_chardev_backends() and
char_get_class(). The alias field is moved outside in a ChardevAlias[],
similar to QDevAlias for devices.

"kind" and "parse" are moved to ChardevClass ("kind" is to be removed
next)
