[enhancement] Add multi-value properties

[Perlsowisdom]

Description

It would be super useful if properties support multiple values. Specifically, if there was a select property drop-down style type like what anytype created:

And if there was a multiple select type property.

The multiple select could be repurposing the tag property allowing it to be named as a different key.

Use case

If a user wanted to log their book notes, the select property could be used to toggle between to-read, reading, or read. In general, this would be useful for general task management purposes. The multi-select would be useful if you wanted to specify what genres a book was in, or who was working on a certain task.

Anything else?
