Apply base_bind_rewriters to //net/proxy_resolution/proxy_resolver_v8_tracing.cc

*** Note: There is no behavior change from this patch. ***

This CL replaces calls to base::{Bind,BindRepeating} with calls to
base::BindOnce, and removes calls to base::AdaptCallbackForRepeating
when the returned base::RepeatingCallback is immediately converted
to a base::OnceCallback.

This CL was uploaded by git cl split.
