Permissions by user field

Minor adjustment. Remove user_access route from tac_lite.links.task.yml.

Patch updated. We can not get the uid from a presave-hook (when the account is first created), but it should work in an update-hook.

Patch #5 works for using Drupal 10.2.5

I do think this is a major feature for tons of reasons:

• better user experience when setting user's access: all is on the user's form
• it's a field: you can build a view to list who has access to what, display an indicator on the user's profile...
• it can be bundled with Include all taxonomy terms (https://dgo.to/3203718#comment-15097728) patch
• it remove the need for several other useful patches (because it removes the extra user tab):
• Property $uid is deprecated (https://dgo.to/3390089)
• Displayed in default theme (https://dgo.to/3385159)
• Option to use checkboxes (https://dgo.to/3399923)
• Separate permissions for user access (https://dgo.to/3218360)

An update hook will be needed for existing tac_lite setups as all users accesses need to be set again.
Syncing "tab" and "field" could be the best of both worlds… something that has been imagined in issue https://dgo.to/2057915
