[jdk21u-dev] RFR: 8361613: System.console() should only be available for interactive terminal

[Goetz Lindenmaier]

Had to adapt change to JdkConsoleProviderImpl.java. Touched method looks quite different.

Omitted change to test/jdk/java/io/Console/DefaultCharsetTest.java
which was added by  "https://bugs.openjdk.org/browse/JDK-8341975: Unable to set encoding for IO.println, IO.print and IO.readln" in 24
Omitted change to test/jdk/java/io/Console/LocaleTest.java
which was added by "https://bugs.openjdk.org/browse/JDK-8330276: Console methods with explicit Locale" 23. Has CSR and Release Note.
Omitted change to test/jdk/java/lang/IO/IO.java
which was added by "https://bugs.openjdk.org/browse/JDK-8344706: Implement JEP 512: Compact Source Files and Instance Main Methods"

Trivially resolved ModuleSelectionTest.java.

Omitted change to test/jdk/jdk/internal/jline/JLineConsoleProviderTest.java
which was added by "https://bugs.openjdk.org/browse/JDK-8331535: Incorrect prompt for Console.readLine" in 23. Backport?
Omitted change to test/jdk/jdk/internal/jline/LazyJdkConsoleProvider.java
which was added by "https://bugs.openjdk.org/browse/JDK-8333086: Using Console.println is unnecessarily slow due to JLine initalization" in 23.
test/jdk/jdk/internal/jline/RedirectedStdOut.java cannot be deleted/moved
It was added by "https://bugs.openjdk.org/browse/JDK-8330998: System.console() writes to stderr when stdout is redirected" in 23.

I'm not sure what to do with files locale.exp and defaultCharset.exp.  They would be used by the omitted tests.
