This commit fixes a number of bugs in `file_size_restriction` settings and does a little of refactoring to reduce duplicated code in site setting types (the refactoring is necessary to fix one of the bugs).
The bugs in `file_size_restriction` settings that are fixed in this commit:
1. Save/cancel buttons next to a `file_size_restriction` setting are shown upon navigating to the settings page without changes being made to the setting
2. Cancel button that discards changes made to the setting doesn't work
3. Reset button that resets the setting to its default doesn't work
4. Validation error message isn't cleared when resetting/cancelling changes
To repro those bugs, navigate to `/admin/site_settings/category/files` and observe the top 2 settings in the page (`max image size kb` and `max attachment size kb`).
Internal topic: t/134726.
This removes all trivial usages of the `{{action}}` keyword (the helper form, not the modifier form), where trivial means:
1. It's a co-located component (`.hbs` next to `.js`)
2. The JS file has a default export that is native class
3. `{{action "foo"}}` or `(action "foo")` with no extra arguments
4. There is a corresponding `foo()` method defined on the class (not inherited, etc)
There are more usages that is slightly more involved (with arguments, etc) that we can deal with, but this PR seems big enough so I just included the easiest cases here.
To aid review, each file is converted in an individual commit, and the matching method is temporary annotated with `@__action__` instead of the normal `@action`. This forces a git diff when it is already annotated as `@action`.

1. Use `this.` instead of `{{action}}` where applicable
2. Use `{{fn}}` instead of `@actionParam` where applicable
3. Use non-`@` versions of class/type/tabindex/aria-controls/aria-expanded
4. Remove `btn` class (it's added automatically to all DButtons)
5. Remove `type="button"` (it's the default)
6. Use `concat-class` helper
