Jordan Justen 5c4c8bdc4c iris/batch: Add support for engines contexts
As described in "intel: Add intel_gem_create_context_engines", this
should make it easier to support an I915_ENGINE_CLASS_FOO engine in
the future. For example, maybe something like:

https://gitlab.freedesktop.org/drm/igt-gpu-tools/-/commit/98c3bbd5b54eb9914329155bfeddd0ad88f96ad2

Reworks:
 * Tweak engine counting logic (s-b Ken)
 * Tweak init of engine_classes in iris_init_engines_context (s-b Ken)
 * Add STATIC_ASSERT on engine_classes (Jordan)
 * Paulo: Call iris_hw_context_set_unrecoverable() for engines context
 * Rename to has_engines_context (s-b Paulo)
 * Jordan: Handle creating a new engines context when the context needs
   to be replaced.
 * Ken: Tweak context destroy code paths.
 * Call iris_lost_context_state on every batch. (s-b Ken)

Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://mesa3d.org/install.html>`_), but the recommended way is to use

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.net/dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
