lis2dw12: Add support for lis2dw12 accelerometer

[bigtreetech]

lis2dw12 is an accelerometer from STMicroelectronics
With better performance than the ADXL345 according to the datasheet.

This Build test / build (pull_request) error is Klipper image is too large.
Using Optional features (to reduce code size) locally to disable other features and enable Support external sensor devices can successfully build

Thanks. In general it seems fine to me. I have a few comments:

1. The build tests need to pass - try adding WANT_DISPLAYS=n and/or WANT_SENSORS=n to test/configs/ar100.config to see if that fixes the issue. (Or perhaps @eliasbakken has a suggestion here.)
2. The new klippy/extras/lis2dw.py and src/sensor_lis2dw.c files need a copyright statement at the top of the file. If you don't want to add your copywrite, you can copy the copyright statements from klippy/extras/adxl345.py and src/sensor_adxl345.c respectively.
3. The docs/Config_Reference.md file should be updated with [lis2dw].

Also, @dmbutyugin do you have any comments on this PR?

I think WANT_DISPLAYS is already deselected. Deselecting WANT_SENSORS would also remove adxl345, which some people might be using with ar100. Is it an option to increase the granularity a bit? Either that or remove this new accelerometer by using the "HAVE_LIMITED_CODE_SIZE" setting to make the ar100 pass.

1. According to the suggestion of @eliasbakken, the configuration of WANT_LIS2DW has been added. And now all build tests can pass.
2. The copyright has been added as required.
3. The instructions of how to configure LIS2DW has been added in docs/Config_Reference.md.

Thanks. It looks fine to me. I'll give a couple of days to see if there are additional comments - otherwise I'll look to commit.

Cheers,

Thanks. I had just a few comments. I didn't test the accelerometer though, so I cannot comment whether and how it works either in the current state or with the suggested mode change. Besides that, I don't have any major feedback for the support of this accelerometer.

Thanks.
