Feature Request: ability to have DEBUG_TB_ENABLED=True but some way to exclude arbitrary Flask endpoints

[jerrydboonstra]

I like to have this toolbar turned on in my cloud -based test environments, but I don't want it to appear on, say, a login page.

It would be wonderful to have either a DEBUG_TB_DENY_PATHS: list[str] in configuration, or a @deny_debugtoolbar route annotation.

Yes, this would be a very useful feature. Not sure why there isn't a way to disable this on a per-route basis? I have some routes that don't make sense to have debug bars.
