[ozone] Install ozone message filter in the gpu process in GpuChildThread()

[ozone] Install ozone message filter in the gpu process in GpuChildThread()

As a follow up to https://codereview.chromium.org/847203004/ we are
installing the message filter early enough to be able to process all
messages on IO. Currently there is a race condition between filter
getting installed and messages arriving and forwarded to main.

This installs the filter before the channel is connected preventing
the issue.
