configure: Poison all current target-specific #defines
We are generating a lot of target-specific defines in the *-config-devices.h
and *-config-target.h files. Using them in common code is wrong and leads
to very subtle bugs since a "#ifdef CONFIG_SOMETHING" is not working there
as expected. To avoid these issues, we are already poisoning many of the
macros in include/exec/poison.h - but it's cumbersome to maintain this
list manually. Thus let's generate an additional list of poisoned macros
automatically from the current config switches - this should give us a
much better test coverage via the different CI configurations.
Note that CONFIG_TCG (which is also defined in config-host.h) and
CONFIG_USER_ONLY are special, so we have to filter these out.
