hex format specifier is not applied to array elements in EE

[ivanbasov]

Steps to Reproduce:

1. Execute the following code

static void Main(string[] args)
{
    var a = new byte[] { 136, 128, 129, 185, 21 };
   Debugger.Break();
}

2. Type a, h in Expression Evaluator where h specifies applying a hex formatter.

Expected Behavior:
Array and array elements are displayed in hex in EE.

Actual Behavior:
Array is displayed in hex in EE. Array elements are displayed in decimal form.

This is a regression from the legacy EE (see the screenshot of the expected behavior).
