configure: move accelerator logic to meson
Move to meson the code to detect the presence of accelerators, and
to define accelerator-specific config-target.h symbols.
The logic for now is duplicated in configure because it is still
in use to build the list of targets (which is in turn used to
create the config-target.mak files). The next patches remove it.
