App history API to navigation API rename (1/n)

[chromium-wpt-export-bot]

See WICG/navigation-api#83 and WICG/navigation-api#203 for context.

This CL implements the following renames:

• window.appHistory → window.navigation
• appHistory.current → navigation.currentEntry
• appHistory.updateCurrent() → navigation.updateCurrentEntry()
• appHistory currentchange event → navigation currententrychange event
• appHistory.goTo() → navigation.traverseTo()

Notably, window.navigation has to be [Replaceable], as otherwise various internal tests that do var navigation = ... start failing.

No files are renamed at this point (including test files). No classes/IDL interfaces are renamed either.

Thus, the majority of this renaming is done in the web platform tests corpus, and to method names of the AppHistory C++ class.

Some affected tests had inconsistent (flaky) results:

Unstable results

These may be pre-existing or new flakes. Please try to reproduce (see the above WPT command, though some flags may not be needed when running locally) and determine if your change introduced the flake. If you are unable to reproduce the problem, please tag @web-platform-tests/wpt-core-team in a comment for help.

@past Pinged the owner on the chromium CL. Can you pls admin merge this?

There is a second CL depending on this. Now the exporter is red.

Per the author: Firefox does not implement this API, so any flakes there are do to that. It'd be best to just merge it anyways, regardless of Firefox flakes.
