Meta: specs using "page visibility change steps"

[marcoscaceres]

The "page visibility change steps" state:

It would be better if specification authors sent a pull request to add calls from here into their specifications directly, instead of using the page visibility change steps hook, to ensure well-defined cross-specification call order. As of the time of this writing the following specifications are known to have page visibility change steps, which will be run in an unspecified order: Device Posture API, Screen Orientation API, and Web NFC. [DEVICEPOSTURE] [SCREENORIENTATION] [WEBNFC]

Creating this meta issue to track other specs.

• Geolocation - Geolocations uses "page visibility change steps" #7362
• Screen Wake Lock - editorial: Adapt to Page Visibility spec integration into HTML w3c/screen-wake-lock#332
