chplSerializer does not output domains as expected

[mppf]

Since ChplFormat / chplSerializer exist to emit objects in a similar manner to Chapel source code, I would expect it to emit a domain in the same format as a domain literal.

For example:

use IO;
use ChplFormat;

var D = {1..10};

stdout.withSerializer(new chplSerializer()).writeln(D);

This emits

["1..10"]

But I would expect it to emit

{1..10}

Perhaps we could apply whatever exception we are using for the default serializer for ranges also to the chplSerializer here?

This is an unintended side effect of #23392 , which changed some IO behavior to print out domains as lists and ranges as strings when the serializer is not the default serializer.

I'll take a look at updating the chplSerializer implementation to add an exception for ranges and domains.

I'm throwing the 'user issue' label on this since it sounds like @redhatturtle hit this on this Discourse thread (which may have led @mppf to post this?) and the 'bug' label since @benharsh indicated that it was an unintentional change in behavior.
