Use a SimpleJsonSerializer in the FileSplitter (#3262)

Browse Source 
* Use a SimpleJsonSerializer in the FileSplitter

* To avoid extra dependency for Jackson when we
serialize `FileSplitter.FileMarker` to JSON, use
a `SimpleJsonSerializer` instead.
* Fix `SimpleJsonSerializer` to escape a `\` symbol from property values
since it is used for quoting string values in the final JSON

* * Document the change

When `markersJson` is true, the markers are represented as a JSON string, as long as a suitable JSON processor library (e.g Jackson) is on the classpath.
When `markersJson` is true, the markers are represented as a JSON string (using a `SimpleJsonSerializer`).
Version 5.0 introduced the `firstLineAsHeader` option to specify that the first line of content is a header (such as column names in a CSV file).
The argument passed to this property is the header name under which the first line is carried as a header in the messages emitted for the remaining lines.

=== File Changes
The `FileSplitter` doesn't require a Jackson processor (or similar) dependency any more for the `markersJson` mode.
It uses a `SimpleJsonSerializer` for a straightforward string representation of the `FileSplitter.FileMarker` instances.
See <<./file.adoc#file-splitter,FileSplitter>> for more information.
