configure.ac/meson.build: Add options for library suffixes

When building the Chrome OS Android container, we need to build copies
of mesa that don't conflict with the Android system-supplied libraries.
This adds options to create suffixed versions of EGL and GLES libraries:

libEGL.so -> libEGL${egl-lib-suffix}.so
libGLESv1_CM.so -> libGLESv1_CM${gles-lib-suffix}.so
libGLESv2.so -> libGLES${gles-lib-suffix}.so

This is similar to what happens when --enable-libglvnd is specified, but
without the side effects of linking against libglvnd.  To avoid
unexpected clashes with the suffixed appended by libglvnd, make it an
error to specify both --enable-libglvnd and --with-egl-lib-suffix.
