Subject: [PATCH] chore(ci): Prepare macOS workflows for dual Cirrus/Bitrise
 runners
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add runner_provider matrix dimension to all macOS CI jobs so they can
run on both Cirrus and Bitrise. Bitrise jobs use continue-on-error so
they won't block CI. Jobs won't actually run on Bitrise yet until the
pool is provisioned — this prepares the ground to enable it.
