Allow copying with ANSI escape code control sequences (#17059)
## Summary of the Pull Request

This extends the copy command to be able to include control sequences,
for use in tools that subsequently know how to parse and display that.

## Detailed Description of the Pull Request / Additional comments

At a high level, this:
- Expands the `CopyTextArgs` to have a `withControlSequences` bool.
- Plumbs that bool down through many layers to where we actuall get
  data out of the text buffer.
- Modifies the existing `TextBuffer::Serialize` to be more generic
  and renames it to `TextBuffer::ChunkedSerialize`.
- Uses the new `ChunkedSerialize` to generate the data for the copy
  request.

## Validation Steps Performed

To test this I've manually:
- Generated some styled terminal contents, copied it with the control
  sequences, pasted it into a file, `cat`ed the file and seen that it
  looks the same.
- Set `"firstWindowPreference": "persistedWindowLayout"` and
  validated that the contents of windows are saved and
  restored with styling intact.

I also checked that `Invoke-OpenConsoleTests` passed.
