[Security Solution] [Detections] Only display actions options if user has "read" privileges (#78812)

* adds new 'can_read_actions' property to privileges api

* only display rule actions piece if user has 'read' privileges for actions

* display dropdown with custom text telling user they do not have read privileges for actions

* fixes type error

* update tests

* utilize application capabilities instead of making a server request

* remove changes to route tests

* don't show form unless user has read permissions for actions, display text saying user is missing required privileges

* pr feedback: refactor logic for rendering form fields
