Servicifying net::MojoProxyResolverFactory.

Making net::MojoProxyResolverFactory a service and removing its use of
UtilityProcessHost.

Also renaming the interface implementations from MojoProxyResolverImpl/
MojoProxyResolverFactoryImpl to ProxyResolverImpl/
ProxyResolverFactoryImpl as is customary.

Also moving files not needed by the proxy service from
services/proxy_service to content/:
proxy_resolver_factory_mojo.[h,cc]
proxy_service_mojo.[h,cc]
test_mojo_proxy_resolver_factory.[h,cc]
mojo_proxy_resolver_factory.h
