Description:
All our pixels currently send the ATB as a parameter but some pixels should not send such information, for instance EMAIL_TOOLTIP_DISMISSED, EMAIL_USE_ALIAS, , EMAIL_USE_ADDRESS.

This PR:

• Adds a PixelAtbRemovalInterceptor that is added to the pixel okHttp instance that will redact the atb parameter from the pixel if necessary
• Adds an inline interceptor to the pixel okHttp instance that just logs the final request url that is sent so that we can easily check in the console in debug builds
• we already had some timbers that logged the pixel params etc, but as we are modifying the request using an interceptor, those timber may not contain the request params that are actually going out
• Adds PixelAtbRemovalInterceptorTest that verifies that for all pixels in AppPixelName only contain the atb param those which are supposse to

Steps to test this PR:

1. install from this branch
2. filter logcat by Pixel url request:
3. add your personal duck address in settings -> Email Protection
4. navigate to github.com
5. in the email address input field dax should appear
6. click on dax
7. dismiss the dialog that appears
8. verify that Pixel url request: https://improving.duckduckgo.com/t/m_e_t_d_android_phone?appVersion=5.92.1&cohort=internal_beta&test=1 appears in logcat

• the important thing is that pixel should be m_e_t_d and atb param is not in url

1. click on dax
2. click on User yourEmail@duck.com
3. verify that Pixel url request: https://improving.duckduckgo.com/t/m_e_uad_android_phone?appVersion=5.92.1&cohort=internal_beta&test=1 appears in logcat

• the important thing is that pixel should be m_e_uad and atb param is not in url

1. click on dax
2. click on Generate private address
3. verify that Pixel url request: https://improving.duckduckgo.com/t/m_e_ua_android_phone?appVersion=5.92.1&cohort=internal_beta&test=1 appears in logcat

• the important thing is that pixel should be m_e_ua and atb param is not in url

If you remove the PixelAtbRemovalInterceptor form the okHttp instance and perform the test steps above, all three pixels should have the atb param

The PixelAtbRemovalInterceptorTest should ensure that no other pixel is affected by this change

Can we use here AppPixelName.EMAIL_TOOLTIP_DISMISSED.pixelName, etc instead of the actual values?

I think it makes sense. Will change

Looks good, just left a comment for better readability to use AppPixelName.EMAIL_TOOLTIP_DISMISSED.pixelName instead the string directly.
