Route Grape::Json through the non-deprecated MultiJSON API

multi_json 1.21.0 deprecated the `MultiJson` constant (in favor of
`MultiJSON`) and `MultiJSON.dump` (in favor of `generate`), removed in
2.0. Grape detected the backend via `::MultiJson` and called `dump`, so
users on multi_json >= 1.21 saw deprecation warnings (#2763).

Detect `::MultiJSON` and give `Grape::Json` a small facade whose `dump`
delegates to `MultiJSON.generate` (byte-identical output), re-exposing
`parse` since the facade no longer inherits MultiJSON's methods. Behavior
is unchanged on every path; the stdlib and legacy multi_json fallbacks
are untouched.

Following #2762 (Grape standardizes on `parse`, never `load`, for JSON),
the two remaining `Grape::Json.load` spec helpers move to `parse`, so
`Grape::Json.load` no longer appears anywhere and the facade needs no
`load`.
