feat(plugin-workflow): change to unlimited depth preloading associations in workflow (#2142)

* refactor(plugin-snapshot): move AppendsTreeSelect component into client package

* refactor(plugin-workflow): change all appends fields select to AppendsTreeSelect

* refactor(plugin-workflow): change appends and toJSON logic on server side

* fix(plugin-workflow): fix toJSON logic and build error

* fix(plugin-workflow): fix missing component injection

* fix(plugin-workflow): fix cycle association in variables

* refactor(client): change AppendsTreeSelect to lazy load

* fix(client): fix lazy load in option
