(enhancement) Hide individual icons in toolbar

[rafareusch]

Hey

I love having subviews in my HA, but hate that people can search any entity both via search and assist.
I know theres a configuration to hide icons (hide_toolbar_action_icons), but it makes (almost?) impossible to make a quick edit with the Companion App, only via browser to add the ?Edit=1 at the end of URL

I think to have this ability to hide indiviudal icons in the tool bar would be a good configurable options!
