Remove dead end in parser for __ctrlFlow(enable=false) and enable=false

[AntoineGautier]

The elements annotated with __ctrlFlow(enable=false) (deadEnd property) or enable=false with literal boolean assignments are not parsed in server/src/parser/parser.ts.

let childInputs =
  this.enable === false || this.deadEnd
    ? []
    : typeInputs[this.type]?.inputs || [];

This must be changed because these elements may contain parameters used in bindings for, e.g, enable annotations.

The dead end must be moved to the client interpreter.
If any parent in the instance tree is disabled, the declaration must not be displayed.
