Make Terminal is configurable

### Description

Currently I am using Windows, I do not find an option in terminal to select which Terminal tools is used in the backend.

It seems it use a Cygwin like shell in the Terminal window, I have installed a Cygwin in my system.

For Windows users, powershell is preferred, and Linux maybe bash is better.

Like IDEA, it is better provide a selectable(dropdown list of all terminal tools that detected by NetBeans IDE) input file box for users to choose it.

Start by locating NetBeans' Terminal settings and the backend that launches the current shell, then inspect how platform-specific tools are discovered. The issue is done when users can select an available terminal tool, with the choice used for subsequent terminal sessions on Windows and Linux.
