gl_renderer: log EGL features

Log EGL features similar to how GL ES features are logged: listing just
the ones weston tests for.

This replaces some log messages from gl-renderer.c that become
redundant or belong with EGL better.

has_native_fence_sync and has_wait_sync are not logged, because missing
them already logs warnings.
