loader: Load a splash screen if "splash" variable is defined

Load a splash screen that vt(4) can use if the "splash" env variable is defined.
For now only png is supported and decoding is done in loader and not in kernel
compared to splash screen support in sc(4).

For using this add:
boot_mute="YES"
splash="/boot/images/freebsd-logo-rev.png"
in loader.conf

We have the call to gfx_interp_ref to bring in the .o so that we get the
linker set item to add the language bindings at the right time. Where we
call it is not the right time... So the _ref name is better. Change it
before we have too many others like it.
