RFR: 8332314: Add window size configuration option to JavaShellToolBuilder interface

[Archie Cobbs]

When launching JShell programmatically (i.e., from a Java program instead of the command line) for an interactive session, it's not currently possible to inform JShell what the terminal window's dimensions are. As a result, JShell defaults to 80x24 and line editing becomes almost impossible because of the scrambled screen contents unless you happen to be using an 80x24 window, which these days is very unlikely.

This patch adds a new method `JavaShellToolBuilder.windowSize()` which allows passing a "hint" for the number of rows & columns.
