Add extra safety check to the EGL context setup.

Adds a check to make sure eglChooseConfig actually
found a valid config. Besides checking for EGL errors,
we also have to handle the case when no matching configs
are found, i.e when num_config is 0.

Bump min picture version.

Chrome Stable is M39, which produces picture format v35:
    https://chromium.googlesource.com/skia/+/chrome/m39/include/core/SkPicture.h

We don't need any code to deal with pictures older than v35.

(When M40 goes stable, we can step up to v37, the current latest version.)
