Add CODE_COVERAGE option to enable coverage instrumentation in builds.
Add new CI job to upload coverage reports to CodeCov.io.
Reports can be found by navigating the codecov.io UI, or by going to
the URL printed at the end of the "Code Coverage" CI job. More CodeCov
integration could be set up later once we have coverage reporting on the
main branch.
This reduces the time to run tests from 5-9 minutes down to 3-4 minutes.
`nproc` is returning `1` on the CI node which is processing our
config.yml. In the absense of a better way of getting the number of CPUs
on our executor, just hardcode it.
We actually have 16 cores on our 2xlarge executors, but higher
parallelism in tests appears to cause oid to sometimes fail with SIGILL.
I'm still investigating this problem.
This will give us more flexibility later, e.g. allowing different steps
for GCC and Clang (as needed for code coverage), or letting us
parallelise our tests across multiple machines.
Folly updated the signature of small vec types here:

I needed to add a new 'using' for policy_size_type, as this is commonly
used with this new template parameter.
these tests were skipped as they can't record the dynamic size. however,
there isn't a dynamic size to report as the type of the pointer is void.
accept a dynamic size of 0 as it's the best we can do with no type
knowledge.
The `oil_skip` test option was added for tests that don't work under OIL
but do work under OID. However, we now have two classes of `oil_skip`ped
tests: those that could be fixed, and those that will never work.
Increase clarity by not generating the tests which do not make sense at
all, leaving us with a cleaner set of skipped (and fixable) tests.
The extern repos are currently cloned with SSH. This means that
attempting to clone them on a system that doesn't have an SSH key which
GitHub accepts fails. Change them to HTTPS as they're read only anyway.
