vgabios: Make VBE code independent of bochsvga.

Introduce new global variables (VBE_enabled, VBE_total_memory,
VBE_capabilities, VBE_framebuffer) to replace the need for function
calls that were specific to bochsvga.

Replace info received from bochsvga_mode_info with info found in
vgahw_find_mode.
