This updates balena lint to the latest version to enable eslint support
and unblock Typescript updates. This is a huge number of changes as the
linting rules are much more strict now, requiring modifiying most files
in the codebase. This commit also bumps the test dependency `rewire` as
that was interfering with the update of balena-lint
Change-type: patch
RPI firmware configuration allows repeating overlays to define
configurations on multiple devices. For instance, for configuring
multiple `ads` devices, `config.txt` needs to be setup this way
```
dtoverlay=ads1115,addr=0x48
dtoverlay=ads1115,addr=0x49
```
Before this change, the supervisor would interpret both lines as
belonging to the same overlay, preventing users from configuring multiple
devices, and leading to a loop when trying to apply configurations with
repeated overlays coming from the cloud side.

This commit completes the list of default / board-wide dtparams
to include some `baudrate` and `vc` i2c params.

Previously, getBootConfig() of the config.txt backend was omitting
array configurations such as gpio settings, thus resulting in the SV
mistakenly assuming that boot config had not been applied, since gpio
would not be in current config.txt config but would be in target config.
This resulted in SV entering an infinite loop of attempting to apply the
gpio config when it wasn't necessary.

While ordering is important in the RPI firmware configuration file (config.txt),
some dt params are by default considered part of the base dt overlay
if they are not used by other overlays.
Unfortunately the [list of dtparams](https://github.com/raspberrypi/firmware/blob/master/boot/overlays/README#L133)
is too long to add all of them as exceptions, but we can add the params
used in the default config.txt provided in OS images, to avoid reboots
when updating to this new supervisor and correctly parsing the
provisioning config.txt as variables.
While this addition handles most common scenarios, there is still a
chance a user may have use other base overlay dt params in the initial
config, in which case those will be interpreted according to the
relative ordering

As the Supervisor is a privileged container, it has access to host /dev, and therefore has access
to boot, data, and state balenaOS partitions. This commit sets up the framework for the following:
- Finds the /dev partition that corresponds to each partition based on partition label
- Mounts the partitions into set mountpoints in the device
- Removes reliance on env vars and mountpoints provided by host's start-balena-supervisor script
- Simplifies host path querying by centralizing these queries through methods in lib/host-utils.ts
This particular changes env vars for and mounts the boot partition.
Since the Supervisor would no longer rely on container `run` arguments provided by a host script,
this change moves Supervisor closer to being able to start itself (Supervisor-as-an-app).

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.

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
