role=textbox elements should get InteractionRegions

https://bugs.webkit.org/show_bug.cgi?id=267544
<rdar://117607868>

Reviewed by Anne van Kesteren.

Add `TextField` to the list of roles that can be used instead of
`cursor: pointer;`, this is what `role=textbox` maps to.

* Source/WebCore/page/InteractionRegion.cpp:
(WebCore::shouldAllowAccessibilityRoleAsPointerCursorReplacement):
Add a `TextField` case.

* LayoutTests/interaction-region/aria-roles-expected.txt:
* LayoutTests/interaction-region/aria-roles.html:
Add a test covering this change.
