treewide: Convert macro and uses of __section(foo) to __section("foo")

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.

Remove the quote operator # from compiler_attributes.h __section macro.

Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

Conversion done using the script at:

x86/boot/video: Move the 'video_segment' variable to video.c

video.c is the only real user of the 'video_segment' variable,
so move it to video.c and make it static.

x86, boot: Use __attribute__((used)) to ensure videocard structs are emitted

It looks like GCC will always emit an object that is marked with an
explicit section, although the documentation doesn't say that and we
possibly shouldn't be relying on it.

Clang does *not* do so, so add __attribute__((used)) to make sure.

x86, setup: remove obsolete pre-Kconfig CONFIG_VIDEO_ variables

There were a set of pre-Kconfig configuration variables defined in the
video code. There is absolutely no evidence that they have been
tweaked by anybody in modern history, so just get rid of them and hope
nobody notices. If someone does complain, these should be made real
Kconfig variables.

x86 setup: display VESA graphics modes in vga=ask menu

Display VESA graphics modes, with their mode IDs, in the vga=ask
menu. Most VESA mode numbers are platform-dependent, so it helps to
have an easy way to display them.
