Mojo interface for Leak Detector on remote process

Mojo interface for Leak Detector on remote process

This interface allows an instance of the Runtime Memory Leak Detector
(components/metrics/leak_detector) to run on a non-browser process, such
as a tab (renderer) process. The interface provides two function APIs:

- GetParams(): Returns the profiling parameters used for initializing
  LeakDetector.
- SendLeakReports(): Passes an array of leak reports in serialized proto
  format (strings) to the browser process, where they can be attached to
  the UMA protobuf.

A revert of this CL (patchset #2 id:20001) has been created in
https://codereview.chromium.org/2055393002/ by sque@chromium.org.

The reason for reverting is: Need to re-submit mojom interface and
implementation in single CL, and get security review from IPC owners..
