[wire-service] Remove experimental WireContextEvent event name

[caridy]

As today, we use an experimental mechanism to provide a dummy-context mechanism. This relies on a magic string value "WireContextEvent" that can be used to dispatch a DOM event from a wire adapter.

This is not longer needed, and should be removed in favor of the formal context mechanism specified here salesforce/lwc-rfcs#6.

Hi, not sure if related, but if debug mode is turned on, any time you wire the CurrentPageReference you get an error. Here's an example that happens in the lwc-recipes.

Invalid event type "WireContextEvent" dispatched in element .

@jflowers45 no, your specific question was answered here: #1591 (comment), and this issue is pending to be closed as soon as we merge #1459, which should happen in the next few days, with that change, there will be no more WireContextEvent.
