[CI] Add SW build using make targets

Add software build targets to Azure pipelines. This may
eventually change once we add system test coverage to CI.

To run the flow in local mode:

```console
$ cd ${REPO_TOP}
$ ci/run_sw_build.sh
```

By default TOOLCHAIN_PATH points to /tools/riscv. If overridden,
the script will fetch the toolchain if needed before running the
build, e.g.:

```console
$ cd ${REPO_TOP}
$ TOOLCHAIN_PATH=/tmp/toolchain-path ci/run_sw_build.sh
```

Additional ENVARs:

* `REQUEST_UPDATE`: If set to true, the script will attempt to update
  toolchain to the requested `TOOLCHAIN_VERSION` which defaults to
  `latest`.

Other Comments:

* Why a shell script instead of Python? I expect that once we move
to a new build system, the script will no longer require to hardcode
the target enumeration, so the bulk of the logic will be gone.
I am open to rewriting in Python if we prefer consistency.
