SVGHMI: continue rework of Jump widget to cope with Enable Expressions.
Questioning widget's activity and disability all together.
Now active/inactive/disable masquarade is all managed in widgets_common.
Propagated changes to widget already using activity (buttons)

SVGHMI: rework Jump widget to cope with Enable Expressions.
Relative jumps are not disabled implicitely anymore when pointed HMI_NODE is 0.
Also, "activable()" implementation was enhanced to make it optional.
Edouard Tisserant [Tue, 23 Aug 2022 12:19:44 +0200] rev 3594
SVGHMI: add support for "enable expressions" with arbitrary variable name assignment.
HMI tree paths can be prefixed with a variable name "@name=/MY/HMI/VAR"
Widget declarations can end with a "#" followed by a JS expression that refers to name given to variables.
Widget is disabled if expression's result is false.
Commit includes some more-or-less related generated code refactoring, that should simplify extending widget's variables attributes.
