The declarations for 'vesa_{init,early_init,endboot}' needed by
'xen/drivers/video/vesa.c' and 'fill_console_start_info' in 'vga.c'
are now available by moving the relative code inside 'vga.h'.
While moving the code, the alternative definitions are now guarded by
CONFIG_VGA. The alternative #define-s for 'vesa_early_init' and 'vesa_endboot'
are dropped, since currently they have no callers when CONFIG_VGA is not defined.
This also resolves violations of MISRA C:2012 Rule 8.4.
Fixes: 6d9199bd0f22 ("x86-64: enable hypervisor output on VESA frame buffer")
