Add pixel where auth indicates a hardware missing error

Task/Issue URL: https://app.asana.com/1/137249556945/project/488551667048375/task/1209519141368890?focus=true

Description

Pixels the scenario whereby auth library returns that the required hardware isn’t present. We expected this not to happen because we check hardware in advance but we’ve seen a few reports indicating this might be happening still and we want to understand it more.

Since it’s not an error that’s possible to reproduce naturally, there is a patch that will map user-cancellations of the auth dialog to act as ERROR_HW_NOT_PRESENT errors for testing.

Steps to test this PR

• Apply patch (defined below)
• Add one or more passwords
• Visit the Password management screen
• When prompted to authenticate, cancel instead. Note, this triggers the patch’s changes simulating this error scenario occurring.
• Verify you see autofill_device_auth_error_hardware_unavailable in the logs
• Repeat, and verify autofill_device_auth_error_hardware_unavailable isn’t sent again
