JDK-8299689 - Make use of JLine for Console as "opt-in"
Description
Summary
-------

Making the support for "JLine" based Console as "opt-in"

Problem
-------

The enhancement introduced in JDK-8295803 uses `JLine` library (`jdk.internal.le` module) as the `java.io.Console` implementation by default. This resulted in the performance regression as in the problem description.

Solution
--------

Making the support for `JLine` optional. Only available if the user opts in with `-Djdk.console=jdk.internal.le` system property.

Specification
-------------

N/A. This is the behavioral change only.
Comments
Withdrawn. Replaced with JDK-8299690
