feat(layout): add toggle/open/close directives for layouts with sidenav.

[emoralesb05]

so we can open/close/toggle any sidenav from any child component, we need special directives that access their parent layouts.

with this we can affect the behavior of it, and it also includes [hideWhenOpened] input and a default input to disable/enable the action leveraging the media service

What's included?

• tdLayoutToggle / tdLayoutOpen and tdLayoutClose directives for parent td-layout

• tdLayoutNavListToggle / tdLayoutNavListOpen and tdLayoutNavListClose directives for parenttd-layout-nav-list

• tdLayoutManageListToggle / tdLayoutManageListClose and tdLayoutManageListOpen directives for parent td-layout-manage-list

• feat(docs): better demos and examples for layouts and directive usages.
