Is your feature request related to a problem? Please describe.

NVDA supports many command line parameters however in most cases it performs no validation as to the given parameter being valid in the current context. For example:

• --install and --install-silent should not be accepted when started from sources or when provided to an installed copy
• --create-portable and --create-portable-silent should not be accepted when running from sources, and should give an error when --portable-path is not provided.

Describe the solution you'd like

NVDA should show a warning in these cases.

Describe alternatives you've considered

None.

Additional context

Some options such as --portable-path should not cause a warning even if --create-portable has not been provided since they can be used to prepopulate values in the GUI.
