base: AttestationHooks: Spoof device as Pixel XL for Google Photos

Enables unlimited photos and videos backup (restored
functionality from PixelPropsUtils).

Make this optional via overlay, as it needs to be
disabled on some devices such as Pixel 6 series
in order to utilize its tensor features.

    core: Blacklist Pixel 2017 and 2018 exclusive for Google Photos

    * In this way can use PixelPropsUtils to simulate the Pixel XL prop
      method to use the unlimited storage space of Google Photos
    * Thanks nullbytepl for the idea

    core: Extend Pixel feature blacklist for Google Photos

    Turns out having these breaks Original quality backups.
    Since these indicate that the device is pixel 4 which in turn breaks device spoofing as OG pixel

    core: Blacklist P21 experience system feature from Google Photos

    We want to include the P21 experience flag to enable new features,
    however it seems like Google Photos uses it to decide whether to use the
    TPU tflite delegate. There doesn't seem to be any fallback so we need to
    make sure the feature is not exposed to the app so that a normal
    NNAPI/GPU delegate can be used instead.

    Test: Google Photos editor with PIXEL_2021_EXPERIENCE feature in product
