Switch extension struct members that are sent over IPC to use uint32_t instead of size_t.

size_t's size depends on the architecture. We need IPCs to match as we're now going to support 32 and 64 bit processes communicating on Android.

This is split off from https://codereview.chromium.org/1619363002/.
