loader: Only create gfx 4th bindings when gfx is available

Only create the gfx bindings for 4th when it's compiled into the
loader. We do this with a linker set that only gets brought in to those
loaders that call gfx_framework_init. This calls gfx_interp_md() will
will drag in gfx_loader.c which will add to the linker set that
registers these bindings.

loader: implement framebuffer console

Draw console on efi.
Add vbe framebuffer for BIOS loader (vbe off, vbe on, vbe list,
vbe set xxx).
autoload font (/boot/fonts) based on resolution and font size.
Add command loadfont (set font by file) and
variable screen.font (set font by size). Pass loaded font to kernel.

Export variables:
screen.height
screen.width
screen.depth

Add gfx primitives to draw the screen and put png image on the screen.
Rework menu draw to iterate list of consoles to enamble device specific
output.

Probably something else I forgot...

stand/ficl: Fix testmain

testmain is a userland application intended to be built with standard
headers and whatnot, which we broke.

Fix it by having the testmain build clobber cflags, reducing it to just the
set of defines/includes it needs to build.

Eliminate bsd.stand.mk and -fPIC 32-bit intel builds

OK. We don't really need a bsd.stand.mk, and it was causing a -fPIC
for the toolchain to be added (bogusly) when building on amd64. Pull
all relevant defs back into defs.mk and delete bsd.stand.mk.

This saves about 15-20k on i386 loader and zfsloader which when
combined with Lua give us a lot more stack space in those constrained
environments.
