Allow people to disable the Tag Groups

[stevejburge]

Here's a big potential move: allow users to disable the Tag Groups,

That would leave these options:
https://demo.taxopress.com/alphabetical-tabs/
https://demo.taxopress.com/alphabetical-index/
https://demo.taxopress.com/cloud/
https://demo.taxopress.com/post-list/
https://demo.taxopress.com/post-filter-tags-menu/ and other Toggle Post Filter Examples

Maybe we just have a setting like this on the "Taxonomies" screen.

"Enable Tag Groups to organize terms". This is checked by default. These setting are underneath it:

If you disable the setting, then this happens:

1. In the Gutenberg area, only these options are visible:

• Alphabetical Tabs
• Alphabetical Index
• Simple Tag Cloud
• Post List
• Post Filter items

2. We hide the "Groups" tab in Gutenberg
