Support readonly editors

[Bakual]

Pull Request for Issue #13665 .

Summary of Changes

This PR adds support for readonly/disabled editors

Testing Instructions

• Create a new custom field of the type "editor" and either set the permission so it is not editable (that's the case by default in the contact form) or enabled readonly or disabled in the field options
• Check the item where the field appears
• Test with all three core editors (TinyMCE, Codemirror, None)

Another test:

• Edit the editor formfield spec in a form XML and add a readonly="true" attribute to it. Eg edit /administrator/models/forms/article.xml and change

<field 
	name="articletext"
	type="editor"
	label="COM_CONTENT_FIELD_ARTICLETEXT_LABEL"
	description="COM_CONTENT_FIELD_ARTICLETEXT_DESC"
	filter="JComponentHelper::filterText"
	buttons="true"
/>

to

<field
	name="articletext"
	type="editor"
	label="COM_CONTENT_FIELD_ARTICLETEXT_LABEL"
	description="COM_CONTENT_FIELD_ARTICLETEXT_DESC"
	filter="JComponentHelper::filterText"
	buttons="true"
	readonly="true"
/>

• Check the item

Expected result

Editor should be readonly/disabled.

Actual result

You can edit the content fine.

Documentation Changes Required

https://docs.joomla.org/Editor_form_field_type can now have added attributes "readonly" and "disabled" (they both do the same thing here).

I have tested this item 🔴 unsuccessfully on 7fef75c

with tinymce as the editor I created an editor field for a contact and set it to read only.
I created a new contact and can confirm that the tinymce editor is disabled BUT I then click on the Toggle Editor and can enter text into the editor AND this text will be saved
