Automatically create an automaterialize sensor per automaterializing asset

[Daniel-Vetter-Coverwhale]

I ran across this setting in the docs - https://docs.dagster.io/concepts/assets/asset-auto-execution#auto-materialize-sensors - and I was really hoping that it would allow me to easily turn auto materialization on and off on a per-asset basis. There is some more information here from a request for this a while back - #18133.

I'm thinking now that the use_sensors setting exists (maybe it has for a while, but I just noticed it) and as dagster already parses all the assets during definition maybe that settings behavior can be modified or an additional config piece can be specified to get us individual sensors for each auto materializing asset.

If we could, then maybe we could also get a UI change to allow us to turn auto materialization on or off on the asset page, which would be quite slick, and we could possibly hide the auto materialize sensors from the sensor page.

Thanks!
