Ability to remove Additional notes input

[aasargsian]

We are facing an issue with Additional notes input always being displayed on the booking page. We already gather a lot of information on the booking stage and yet another field can decrease booking conversions.

We would like to be able to remove Additional notes altogether from the event type inputs.

Ideally, we would like to be able to control all Inputs in a separate section of Event settings and be able to turn on/off any inputs.

Tagging @alishaz-polymath since we discussed this on a call today :) I, unfortunately, can't add labels to the issue.
