vt(4): Add support to "downgrade" from eg. vt_fb to vt_vga
The main purpose of this feature is to be able to unload a KMS driver. When going back from the current vt(4) backend to the previous backend, the previous backend is reinitialized with the special VDF_DOWNGRADE flag set. Then the current driver is terminated with the new "vd_fini" callback. In the case of vt_fb and vt_vga, this allows the former to pass the vgapci device vt_fb used to vt_vga so the device can be rePOSTed. Differential Revision: https://reviews.freebsd.org/D687
