Add signature for Chrome 99 on Android phone

Add support for impersonating Chrome 99 on Android 12 (Pixel 6 was
chosen as an arbitrary Android phone to impersonate). The TLS signature
for Chrome on Android is identical to Chrome on Windows. The difference
is in a few HTTP headers ('sec-ch-ua-mobile', 'sec-ch-ua-platform' and
'user-agent').
