[web][camera] Fix permissions check in Firefox (#22855)

# Why

As described in #19485, the current logic for checking camera/microphone permissions does not work in Firefox and leads to a `TypeError` being thrown, as it is not considered a valid permission to check for.

# How

<!--
How did you build this feature or fix this bug and why?
-->
I've fixed this by catching the `TypeError` and returning an undetermined status, so the requesting application can then request permission accordingly.

# Test Plan

<!--
Please describe how you tested this change and how a reviewer could reproduce your test, especially if this PR does not include automated tests! If possible, please also provide terminal output and/or screenshots demonstrating your test/reproduction.
-->
I added a unit test that ensures that we return an undetermined status whenever a `TypeError` is thrown while checking for permissions.
