Implement display options for Duration type

[kgodey]

Problem

The Duration Mathesar type supports the following display options:

• Min unit
• Max unit
• Whether to show unit labels

We will combine this into a single format string.

Solution

(1) We should store these display options in the following format in the display_options field of the corresponding column.

{
  "format": "HH:mm:ss.SSS"
}

(2) We should also validate these so that:

• Only columns of this type can have these display options. They should not be able to be set if the column is of a different type.
• format should be a valid JavaScript duration format.

(3) If the column type is changed, the display options should be deleted.

(4) We should add supported display options to the types endpoint.
