Update browser manifest to require ProcessControl from gpu service

Update browser manifest to require ProcessControl from gpu service

This adds a 'required' entry to the exe:content_browser manifest
for content::mojom::ProcessControl in exe:content_gpu, allowing
the browser to connect to the ProcessControl interface in the GPU
process.

Also fixes a bug in InterfaceRegistry which was causing useful
log errors to be omitted when capability filters would block
interface connection and registration.
