Improve getBattery() algorithm#30

Conversation
These changes are mostly editorial or minor correctness improvements. Notable ones: * Move to the modern definition of secure context * Move to permissions policy instead of feature policy * Avoid "return and continue asynchronously" pattern. It's fine to create the BatteryManager as part of the algorithm (and that in fact matches implementations). * Always have a battery promise available, instead of having it sometimes be null. This is important for integration with prerendering in WICG/nav-speculation#45.

This test does not reflect either the current spec or any implementation. w3c/battery#30 removed the bits from the spec that mandated throwing a SecurityError when the API was used in an insecure origin. Blink does not perform any checks for a security context anyway, although the plan is to switch spec and implementation to using [SecureContext] in the future, as tracked in w3c/battery#15.

…face. In other words, stop exposing this API to insecure origins. This has been discussed since at least 2016 (see #5). #11 made access from an insecure origin throw a SecurityError at a time when the `[SecureContext]` Web IDL extended attribute was not widespread. Unfortunately, the spec change was not accompanied by a change in the implementation(s) and, to this day, Blink's implementation (the only remaining one) continues to expose the API to insecure origins. Years later, #30 was added in the context of the discussions in #15 where it was noted that the spec was still manually throwing a SecurityError when checking if it was called by a secure origin. Besides stopping throwing a SecurityError (which was never implemented), #30 also recognized the current situation by noting that the API _should_ use `[SecureContext]` but did not because it only made sense to do so when the implementation was updated accordingly. This change finally adds `[SecureContext]` to the spec's Web IDL because I am also handling the Blink implementation [1][2]: starting with Chrome 99, users will be warned that using the Battery Status API in an insecure origin is deprecated, and starting with Chrome 103 doing so will no longer be possible. [1] https://chromestatus.com/feature/4878376799043584 [2] https://groups.google.com/a/chromium.org/g/blink-dev/c/w80tJL8uEV8/m/PfrHlvtgAgAJ From a testing perspective, there isn't much to be done: - web-platform-tests/wpt#5871 changed the existing tests to run in HTTPS. - web-platform-tests/wpt#32556 removed the test for the SecurityError exception that never passed. Fixes #15

…face. In other words, stop exposing this API to insecure origins. Even though this API is not new, it provides user information that, transmitted insecurely, can pose a risk to user privacy.
