This PR enables the [`no-action-modifiers`](https://github.com/ember-template-lint/ember-template-lint/blob/master/docs/rule/no-action-modifiers.md) template lint rule and removes all usages of the `{{action}}` modifier in core.
In general, instances of `{{action "x"}}` have been replaced with `{{on "click" (action "x")}}`.
In many cases, such as for `a` elements, we also need to prevent default event handling to avoid unwanted side effects. While the `{{action}}` modifier internally calls `event.preventDefault()`, we need to handle these cases more explicitly. For this purpose, this PR also adds the [ember-event-helpers](https://github.com/buschtoens/ember-event-helpers) dependency so we can use the `prevent-default` handler. For instance:
```
<a href {{on "click" (prevent-default (action "x"))}}>Do X</a>
```
Note that `action` has not in general been refactored away as a helper yet. In general, all event handlers should be methods on the corresponding component and referenced directly (e.g. `{{on "click" this.doSomething}}`). However, the `action` helper is used extensively throughout the codebase and often references methods in the `actions` hash on controllers or routes. Thus this refactor will also be extensive and probably deserves a separate PR.
Note: This work was done to complement #17767 by minimizing the potential impact of the `action` modifier override, which uses private API and arguably should be replaced with an AST transform.
This is a followup to #18333, which had to be reverted because it did not account for the default treatment of modifier keys by the {{action}} modifier.
Commits:
* Enable `no-action-modifiers` template lint rule
* Replace {{action "x"}} with {{on "click" (action "x")}}
* Remove unnecessary action helper usage
* Remove ctl+click tests for user-menu
These tests now break in Chrome when used with addEventListener. As per the comment, they can probably be safely removed.
* Prevent default event handlers to avoid unwanted side effects
Uses `event.preventDefault()` in event handlers to prevent default event handling. This had been done automatically by the `action` modifier, but is not always desirable or necessary.
* Restore UserCardContents#showUser action to avoid regression
By keeping the `showUser` action, we can avoid a breaking change for plugins that rely upon it, while not interfering with the `showUser` argument that's been passed.
* Revert EditCategoryTab#selectTab -> EditCategoryTab#select
Avoid potential breaking change in themes / plugins
* Restore GroupCardContents#showGroup action to avoid regression
By keeping the `showGroup` action, we can avoid a breaking change for plugins that rely upon it, while not interfering with the `showGroup` argument that's been passed.
* Restore SecondFactorAddTotp#showSecondFactorKey action to avoid regression
By keeping the `showSecondFactorKey` action, we can avoid a breaking change for plugins that rely upon it, while not interfering with the `showSecondFactorKey` property that's maintained on the controller.
* Refactor away from `actions` hash in ChooseMessage component
* Modernize EmojiPicker#onCategorySelection usage
* Modernize SearchResultEntry#logClick usage
* Modernize Discovery::Categories#showInserted usage
* Modernize Preferences::Account#resendConfirmationEmail usage
* Modernize MultiSelect::SelectedCategory#onSelectedNameClick usage
* Favor fn over action in SelectedChoice component
* Modernize WizardStep event handlers
* Favor fn over action usage in buttons
* Restore Login#forgotPassword action to avoid possible regression
* Introduce modKeysPressed utility
Returns an array of modifier keys that are pressed during a given `MouseEvent` or `KeyboardEvent`.
* Don't interfere with click events on links with `href` values when modifier keys are pressed

We can't use erb in Ember CLI (since it does not have Ruby) so this has
been ported to use our `javascript:update_constants` rake test instead.
Note we don't have to run this every time a notification type as it's
only used by fixtures to fill in some specific types we test against.
This is where they should be as far as ember is concerned. Note this is
a huge commit and we should be really careful everything continues to
work properly.
