Extend length of feature policy field

Problem/Motivation

When listing a larger number of feature policies to disable the text field does not offer enough space. The string "accelerometer 'none'; ambient-light-sensor 'none'; camera 'none'; document-domain 'none'; document-write 'none'; geolocation 'none'; gyroscope 'none'; legacy-image-formats 'none'; magnetometer 'none'; microphone 'none'; midi 'none'; payment 'none'; sync-xhr 'none'; usb 'none'; wake-lock 'none'; webauthn 'none'; vr 'none'" for example does not fit as it is wider than the current maximum of 255 characters.

Proposed resolution

Extend the length of the field to 2048 characters. This offers about 8x as much space and would be plenty for future extensions. Or no limit at all if that is acceptable. The feature policy spec seems to not list a maximum length.

A tiny patch is attached.
