Support COMMENT for tasks

[rfc2822]

We could support COMMENT with the Comment field for TasksOrg-compatible tasks:

https://github.com/bitfireAT/ical4android/blob/93262f53c2f6e200f73ec9e0ca876e9b120841ae/opentasks-contract/src/main/java/org/dmfs/tasks/contract/TaskContract.java#L1543-L1565

• [x] Add a comment field to Task.
• [x] Task should be able to read the COMMENT property into the comment field
• [x] Task should be able to generate the COMMENT property from the comment field
• [x] DmfsTask: generate COMMENT data row (probably with language null) from Task.comment field
• [x] DmfsTask: process COMMENT data row and fill Task.comment field from it

Sure, I wonder which servers support the COMMENT field already though? Seems like nextcloud (tasks) does not ?

When more clients support it, I guess other clients have a better chance of adopting it. As far as I know, jtx Board also supports it.
