1335859 - Add usage counters to track usage of gecko-only DataTransfer APIs

Status: RESOLVED FIXED

(Core :: DOM: Events, defect)

Description

[Nika Layzell [:nika] (ni? for response)]

There is currently a decent amount of complexity in the DataTransfer{Item{List,},} APIs due to the need to support both the standard APIs, and the moz* APIs (which expose a different backing storage mechanism). 

This patch adds usage counters to these gecko-only APIs such that we can track their usage, and if they drop enough, then potentially remove them from the codebase.

This adds telemetry, so asking for a data collection review.

Since use counters currently don't have expiration rules, please make sure a bug is on file to remove these when you no longer need them. data-r=me
