Run Grape behind Falcon in CI

Add gemfiles/falcon.gemfile and spec/integration/falcon, run on Ruby
3.3, 3.4 and 4.0. The specs start a real Falcon server in-process on a
free port and send it requests with async-http's client:

- 30 concurrent requests, which pause in a before filter, an after
  filter, a custom validator inside array elements and the route block,
  each keep their own params, endpoint instance variables and
  validation error index.
- error! inside an Async task the route waits on responds with its
  status, with and without rescue_from :all (#3023).
- stream sends each chunk of an Enumerator before the endpoint produces
  the next.

Each spec fails under a matching break: a per-thread
ParamScopeTracker, one endpoint shared by every request, error!
throwing instead of raising, Halt as an Exception rather than a
StandardError, and a stream body read into an Array.

A client disconnect or a server stop doesn't cancel a running endpoint:
async-http's servers run the app under defer_stop, so there is no
cancellation to spec.
