Allow role="application" as an interactive ARIA role

[oscarhermoso]

Describe the problem

Unable to resolve accessibility warnings (no-interactive-element-to-noninteractive-role) for elements that are not described by exisiting ARIA widget roles

For example, the Cropper component from Svelte Easy Crop does match any of the other ARIA widget role descriptions.

Describe the proposed solution

This can be resolved by also allowing role="application" as an interactive role.

This is allowed by the spec:

When there is a need to create an element with an interaction model that is not supported by any of the WAI-ARIA widget roles, authors MAY give that element role application.

And also an see example of it out in the wild:
