meson: Print a summary of configured features (if on meson >= 0.53)

GDM has a quite complex configuration and it might be hard to spot some
values from the log, so having a summary makes sense.

Meson introduced it starting from 0.53, but we can enable it without bumping
the dependency by using a dynamic version check.
