While it has been providing rich functionality for Console, it is increasingly difficult to maintain as a Console implementation. In light of the on-ramp feature (https://bugs.openjdk.org/browse/JDK-8344699), which proposes switching `java.lang.IO` class to use `System.in` and `System.out` instead of Console, reverting the default Console implementation to JDK's built-in one in the java.base module is considered desirable. Some tests are modified along with this change, among them test/jdk/java/io/Console/ConsolePromptTest.java changes were contributed by @lahodaj (thanks!)

test/jdk/java/io/Console/ConsolePromptTest.java line 77:

Hello Naoto, I think throwing a `jtreg.SkippedException` might be better here so that it's clear that the test was skipped. There have been recent reporting improvements too which make it easier to notice such skipped tests.
