[jdk20] RFR: 8299689: Make use of JLine for Console as "opt-in"

[Naoto Sato]

Due to the fact that JLine spawns native processes to obtain terminal information on macOS/Linux, we decided to disable the JLine by default for performance degradation reasons. It is still possible to enable it by specifying it on the command line with `jdk.console` system property (not a public one though). Once we have a solution to avoid spawning processes, JLine may be back for use in the future.
