[memory-infra] Deterministic memory dumps

Memory usage of some Chromium components depend on non-deterministic
events such garbage collections. For benchmarks it is important to
remove as much non-determinism as possible to get stable results.

This CL adds a new field to RequestArgs which indicates whether the
request is for a deterministic memory dump or not. Based on this field
memory dump providers perform garbage collection or flushing of cashed
to ensure that the memory usage is more stable.

This CL does not change any of the existing behavior. It simply plumbs
the deterministic option through different layers. Subsequent CL
will update content/browser/devtools/protocol/tracing_handler.cc to
select deterministic mode depending on its parameter.
