Add StandardPathControl, add fileChooser bool argument to explicitly ask or not to have a menu (#2)

* add a StandardPathControl View that use NSPathControl .standard pathStyle

* PopUpPathControl initializer: add fileChooser bool argument to explicitely ask or not to have a menu

* replace @_functionBuilder by @resultBuilder

* StandardPathControl require a non-nil URL

* PopUpPathControl: default fileChooser argument is true to keep the previous behavior
