feat(YouTube - Spoof client): Re-add TestSuite as a spoofing option

[theblackhole]

Feature description

For the YouTube Client Spoof patch, re-add Android TestSuite as a spoofing option in addition to current options (Android VR and iOS)

Motivation

I've been using a branded account as my primary account for years and there are some significant issues with the current spoofing choices offered (also described in #3208):

• either, with the choice of iOS spoof set by default, the viewing history no longer works: we then fall quickly into a cycle where YouTube only recommends videos that have already been viewed (it's quite frustrating)
• either, with the choice of Android VR spoof, the paused or finished video automatically restarts after few seconds, when you change applications, lock the smartphone, etc... (as described by @MelvynEzi , it's always, not random)

Previous versions with Android TestSuite (before #3230) worked fine for me. If there were limitations, I didn't notice them (for my daily use anyway, it's probably different for other people)

I am also experiencing this issue and would like to add a couple of extra reasons to implement it:

1. My non-brand youtube account is attached to my irl name, and as such i have never used it from privacy concerns. I feel like being forced to use it if i want to have a smooth experience on Youtube is a privacy risk which makes me feel unsafe.

2. All my history and subscriptions are tied to my brand account, and migrating them across is very inconvenient.

3. I am a hobbyist youtube creator and as such I need to be primarily focused on my brand account. Switching back and forth is not a good solution.

Please consider these additional reasons when looking into this feature request.

This issue will be obsolete when #3582 is merged, as all known bugs are fixed by that PR

Since #3582 has been released with 4.14.x and since it seems to work as intended without any major issues (especially the ones I described in this PR), I'm closing this PR.

Thanks to everyone involved in #3582 , this is a game changer: no need to force close YouTube every time anymore 🎉

Edit: nvm it's already closed. In any case, thanks to all contributors
