Allow the placement of the cursor in a DAP completion item

[connor4312]

For arrays, I have a completion item that appears as [index] and, when selected, completes

arr.|

to:

arr[|

Ideally I'd like to be able to tack on the closing brace and place the cursor inside the array:

arr[|]

Or complete it as arr[index] and select word "index". Adding a new selection range property to the CompletionItem would let us do this.

I propose to add two optional attributes to the CompletionItem:

  /**
   * Determines the start of the new selection after the text has been inserted (or replaced).
   * The start position must in the range 0 and length of the completion text.
   * If omitted the selection starts at the end of the completion text.
   */
  selectionStart?: number;

  /**
   * Determines the length of the new selection after the text has been inserted (or replaced).
   * The selection can not extend beyond the bounds of the completion text.
   * If omitted the length is assumed to be 0.
   */
  selectionLength?: number;

@connor4312 would this work for you?

Yep, that would work great
