Now that we can link a single-binary with at least two targets (arm, aarch64),
we want to make sure that we expose the same set of machines (later devices and
cpus) than target binaries. For that, we implemented a static filtering based on
target interfaces that each machine will implement to declare which targets have
this machine.

However, we discovered that this static filtering is not enough. Indeed, some
machines and devices do not depend only on target, and their presence can depend
on Kconfig or host/target combination. Thus, our static approach can't work, and
we need something more flexible.

This series adds a new TYPE_TARGET_SPECIFIC, that declare a single function
bool is_available(void). From there, any machine type (and later devices and
cpus) can implement it to override their presence for each target.
We first replace the existing static mechanism with this, and once done, we
cleanup all the old interface. One nice benefit is that we can get rid of
config/targets/*.c files, which saves duplication.

This series was tested by comparing list of machines for all qemu system
binaries, before and after this change, to make sure we don't introduce a
regression.
