Remove ManiphestTaskExtensions

Summary: Ref T418. Maniphest has an obsolete class-based field selector. Replace it with CustomField-based selectors, which use the nice config UI and are generally way easier to use.

Test Plan: Added custom fields; edited and viewed custom fields on tasks. Everything worked as expected.

-If you want to add fields with more specialized validation, storage, or
-rendering logic, you can do so with a little work:
-
-  - Extend @{class:ManiphestAuxiliaryFieldSpecification} and implement
-    your specialized rendering, validation, storage, etc., logic.
-  - Extend @{class:ManiphestTaskExtensions} and return a list of fields which

-  - Set `maniphest.custom-extensions` to the name of your new extensions
