Introduce JSON matrix workflow
Browse files Browse the repository at this point in the history
Introduce and adopt a new method for defining test matrices,
`swift_test_matrix.yml`.

⚠️ Any external adopters of the unit tests, Cxx interop and benchmarks
workflows are automatically opted in to use the new infrastructure.

Motivation:

* The current matrix workflow has the limitation that it only supports
  pre-defined sets of variables which are explored in the test matrix. At
  the moment this is a pre-defined set of Swift versions on Linux and
  Windows.
* Adding more means hard-coding them at multiple levels of the
  workflow hierarchy.
* Currently skipped Windows matrix jobs show up as successes in the
  GitHub UI leading to a misleading impression of good coverage.

Modifications:

Introduce and adopt a new method for defining test matrices,
`swift_test_matrix.yml`. The new method is based around the approach of
defining the test matrix via a JSON object which may be supplied via an
input string from another workflow or from a file on-disk in a
repository.

Taking this approach means that we have the ability to add new targets
to the matrix simply by adding new elements to the JSON array,
increasing flexibility and the scope for future growth.

The unit tests, Cxx interop and benchmarks workflows are all modified to
use the new approach, this opts-in all downstream adopters. This should
be transparent to all downstream adopters.

In order to unify the Linux and Windows jobs I removed the use of the
`container:` GitHub Actions affordance in the Linux jobs which
transparently means all steps are executed within the nested container.
Instead we must manually call in to the docker container which
complicates scripting a little. I tested to see if doing this slowed
down the jobs (perhaps GitHub was caching the docker images more
intelligently) but it does not.

Result:

* More flexible test matrix definitions
* No more false-passes for disabled Windows targets
