Add a native JSON linter.

Summary:
Ref T5297. Utilize `PhutilJSONParser` to create a native JSON linter (native in that it is pure PHP with no external dependencies).

Since [[https://github.com/Seldaek/jsonlint | JsonLint]] is literally a PHP port of [[https://github.com/zaach/jsonlint | jsonlint]], I figured that we should also deprecate `ArcanistJSONLintLinter`. `ArcanistJSONLinter` //should// behave identically to `ArcanistJSONLintLinter`.

Depends on D9634.

Test Plan: Ran the `ArcanistJSONLintLinter` unit tests.
