What kind of version bump will this require?: Minor

**Description**:

Implements Privacy Dashboard message `ReportBrokenSiteShown` which will
trigger a pixel on macOS and iOS

This PR contains a fix for
#1160 which is why
it is stacked on it. Please let me know if this is not the best way to
have this code reviewed.

**Steps to test this PR**:
1. Invoke the breakage form in the two possible ways:
Open the Privacy Dashboard and click on "Report a problem with this
site"
Open the app menu ••• and click on "Report Broken Site” (iOS)

2. Confirm that the pixel `m_report-broken-site_shown` was fired
3. Submit a report
4. Confirm that the pixels `epbf` (iOS) / `epbf_macos_desktop` (macOS)
and `m_report-broken-site_sent` were fired

<!--
Before submitting a PR, please ensure you have tested the combinations
you expect the reviewer to test, then delete configurations you *know*
do not need explicit testing.

Using a simulator where a physical device is unavailable is acceptable.
-->

**OS Testing**:

* [ ] iOS 14
* [ ] iOS 15
* [ ] iOS 16
* [ ] macOS 10.15
* [ ] macOS 11
