junction-elements.rst: Add missing language specifier to literalinclude

A missing language specifier on a literal include directive results in yaml
being rendered as python code. This commit adds the :language: tag to that
directive.

element.py: Cache the result of checking whether an artifact is cached weakly

Normally we'd only need it in the case of scheduling a weakly cached build,
but to allow caching of failed builds we need to be able to distinguish
between cached successes and cached failures
for both strong and weak cache keys.

To allow other cache lookup codepaths to look up via the weak key
requires changes through the call stack to consult which key to use,
and cache invalidation of the saved state when it changes.

element.py: Add metadata to distinguish between successful and failed builds

This just puts the metadata in place,
we're adding code paths to add failed builds later.

Convert call-sites of Element._cached() that assume success

When we later add cached failures it needs to not treat them as successes.

_frontend/widget.py: Render cached failures differently to successes

Cache failed builds

This creates an artifact when element assembly fails too,
and if it's the right kind of exception uses the now-included install directory
similarly to if it had returned successfully.

If there's a failure during install the artifact contains any installed files,
but may contain nothing at all.

_scheduler/queues/buildqueue.py: Skip rebuilding cached failures

This flags up a failure and if run in an interactive prompt
permits the user to attempt a rebuild.

_scheduler/queues: Add failed builds to "done" queue

This allows the scheduler to move jobs from the current queue to the next.

As a result of this change later queues than the build queue
mustn't skip a cached failure, so the logic is specialised to build queues only.
