cromite/build/patches/Disable-conversion-measurement-api.patch

From: uazo <uazo@users.noreply.github.com>
Date: Mon, 15 Nov 2021 09:43:29 +0000
Subject: Disable conversion measurement api

Disable Conversion Measurement API by disabling the flag and removing
support for the AttributionReporting provider. it also removes
the handling of attributions via intents between apps.
This patch enforces the deactivation by preventing the report from
being sent and being saved to disk, although it is currently in uncalled code.
