This PR changes the way the supervisor reads and writes files from /mnt/boot. Reads will
now use the [fatrw utility](https://github.com/balena-os/fatrw/) as a way to minimize corruption of
files in the boot partition, and thus preventing possible bricking of the device.
Since this basically changes the way a lot of configurations are read, this work was being blocked because of
the way tests were being done. While there still remain a couple of legacy tests to be migrated, this PR disables
test:legacy tests when running npm run test, as the work on refactoring those tests is in progress (see #2048) and
fatrw integration is of higher priority.
Change-type: minor
This means that configuration backend tests no longer use stubs and
(mostly) avoid internal dependencies in the tests. Instead of stubs and
mock-fs, the tests use [testfs](https://github.com/balena-io-modules/mocha-pod#working-with-the-filesystem)
which allows working with a real filesystem and ensuring everything is
re-set between tests.
This is the last change needed in order to be able to merge #1971. Here is the list of changes
- [x] Migrate splash image backend tests
- [x] Migrate extlinux backend tests
- [x] Migrate config.txt backend tests
- [x] Migrate extra-uenv config tests
- [x] Migrate odmdata config tests
- [x] Migrate config utils tests
- [x] Migrate device-config tests
Change-type: patch
Use isNotFoundError which converts an error of the default type
`unknown` into NotFoundError if the error is an instance of NotFoundError.
Thrown errors are of type `unknown` by default so we should use methods
with type guards for better type narrowing.

This commit also changes the test:integration command to run integration
tests as different processes. This allows to avoid any test leaking into
each-other because of the use of singletons. This however has the side
effect of tests being slower, but that is a forcing function to refactor
the code.
Newer mocha-pod allows to setup testfs instances at the global
level. This helps the test suite setup as it can guarantee that certain
files will always be available.
Replace test with test:base to make sure integration tests don't run in CI.
Integration tests for the Supervisor fail when not run in container, leading
to an error-exit and cause the Flowzone CI job for Node to fail.
By returning true, the Flowzone Node CI job succeeds, and this is fine even if tests
fail because they will be caught in the Docker job anyway.
Also, combine original npm test script with test:node.
