meson: define driver dependencies

This allow us to encapsulate the compiler and linkage requirements of
each driver in a reusable way. The result will be that each target that
needs a specific driver can simply add `driver_<name>` to its
dependencies line and the necessary libraries and compiler args will be
added. This will allow for a lot of code de-duplication between gallium
targets.
