st/egl: Build a single EGL driver.
This change makes st/egl build a single egl_gallium.so and multiple st_<API>.so and pipe_<HW>.so. When a display is initialized, the corresponding pipe driver will be loaded. When a context is created, the corresponding state tracker will be loaded. Unlike DRI drivers, no ABI compatibility is maintained. egl_gallium, pipe drivers and state trackers should always be distributed as a single package. As such, there is only a single src/gallium/targets/egl/ that builds everything for the package.
