Make Ferret query functions sticky only if their values are not quoted

Browse source 
Summary:
Ref T13509. Currently, functions are "sticky", but this stickness is in the query execution layer.

Instead:

  - move stickiness to the query compiler; and
  - make it so that functions are not sticky if their arguments are quoted.

For example:

  - `title:x y` previously meant `title:x title:y` (and still does). The "title:" is sticky.
  - `title:"x" y` previously meant `title:x title:y`. It now means `title:x all:y`. The "title:" is not sticky because the argument is quoted.

Test Plan: Added unit tests, ran unit tests.
