Clarify Enable Desktop Support checkbox for all project types (#3148)

* Clarify Enable Desktop Support checkbox for all project types

- Java: Has no effect, can be checked or unchecked
- C++: Must be checked for simulation, unit tests, Romi/XRP projects
- Added note about third-party library compatibility
- Removed Python reference (doesn't use this project creator)

Fixes #3146

* Clarify that Enable Desktop Support has no effect on Romi/XRP templates

Per Gold856's comment, the C++ Romi/XRP templates don't have an
includeDesktopSupport variable in the build.gradle, so the Enable
Desktop Support checkbox is a no-op for those templates.

Updated documentation to explicitly state that the checkbox has no
effect for Romi and XRP templates and can be left checked or unchecked.

* Move simulation link to Enable Desktop Support line

Per sciencewhiz's comment, moved the robot simulation introduction link
from the note to the main "Enable Desktop Support" line. The link is a
general reference about simulation, not specifically about conditional
compilation, so it was misleading to have it in the note that discusses
vendor library compatibility issues.

Also removed the conditional compilation reference from the note since
the linked documentation doesn't address that topic.

 5. **Project Name**: The name of the robot project.  This also specifies the name that the project folder will be given if the Create New Folder box is checked.
 6. **Create a New Folder**: If this is checked, a new folder will be created to hold the project within the previously-specified folder.  If it is *not* checked, the project will be located directly in the previously-specified folder.  An error will be thrown if the folder is not empty and this is not checked.
 7. **Team Number**: The team number for the project, which will be used for package names within the project and to locate the robot when deploying code.
-8. **Enable Desktop Support**: Enables unit test and simulation. While WPILib supports this, third party software libraries may not. If libraries do not support desktop, then your code may not compile or may crash. It should be left unchecked unless unit testing or simulation is needed and all libraries support it.

 Once all the above have been configured, click "Generate Project" and the robot project will be created.
