Option to disable AI at the project level

[oliverbarnes]

While having a look at #46846, adding the disable_ai option to the project's settings file didn't get picked up by the settings UI when selecting the project. It'd give me a "project settings out of date" / "manually migrate your settings" warning.

When working on a fix for that issue, the setting didn't get picked up by the fix either :) I had to disable AI at the User level to see it working.

Looking closer, it seems that indeed disable_ai is only defined on global SettingsContent and not on ProjectSettingsContent.

I can see how users might want to disable AI for certain projects and not have to remember to turn it back on for others. Anybody see a down side to it?

Gonna submit a PR for it.
