[UX] Views: Make the "Label for "Any" value" a text field and have it be configurable per view and per exposed filter within each view.

As it is now, this setting is found under /admin/structure/views/settings as a dropdown menu with only "" and "- Any -" as options. This is defined globally for ALL views. That is very limiting and there are quite a few d.org forum topics discussing how to change that, but they involve either using hook_form_alter or hook_form_views_exposed_form_alter or adding a custom language and then "translating" that string

Lets improve this and solve another Drupal UX annoyance by making this setting configurable per view, per exposed filter, as a text field, with default value "Any" so that people can change that as they please.
