vl.c: Move option generation logic into a wrapper file
In vl.c and qemu-options.h we define macros and include qemu-options.def
in order to generate different content. Move the bulk of the def'ing and
undef'ing into a wrapper, this will make it cleaner when we add another
macro in the next patch.
AFAICS undefining GEN_DOCS services no purpose, but I've left it for now.
