ViewsField EntityLink should allow customizing the link template

Problem/Motivation

When building a View, I'd like to add links to various entity pages by choosing a link template, while properly checking access.

This is currently impossible to do for anything but canonical, edit and delete. Even with a "custom HTML" field, I am not aware of any no-code way to confirm access before showing the link.

Steps to reproduce

1. Create a view.
2. Click "Add field".
3. Search for "Link".
4. Notice there are only links for View, Edit, and Delete.

Proposed resolution

Add a new option to the EntityLink plugin for "link_template".

The contrib module views_entity_link already does this, but also includes other options. Core could just have the single option: https://git.drupalcode.org/project/views_entity_link/-/blob/1.1.x/src/Pl...

This would also allow deprecation of the view, edit and delete link classes.

Remaining tasks

Add link_template option to the EntityLink plugin, settings form, and implement.

User interface changes

Add form element above

1. "Absolute URL" for "Link Template".
2. TBD: Text field? or can we lookup available links?

Introduced terminology

None.

API changes

None.

Data model changes

An extra option in the views field field config.

Release notes snippet

TBD.
