Breaking out 2f86e14 from @davidbuzz's larger PR #28514 and adding minor alignment formatting.

Testing

• Tested on esp32 (esp32empty) and esp32s3 (esp32s2stampfly).

Overall this is just to save RAM I imagine?

Judging by Google results, ESP-IDF has a stack canary by default so hopefully we can track future problems back to this if they are reproducible on the bench.

Yes, imagine so. @davidbuzz did the detailed analysis. It does resolve an issue on esp32empty where on master the EKF3 is currently reporting a failure to lack of memory (once you get past the RMT buffer issue by disabling RCIN).

[tpwrules]

Seems to fly okay on the stampfly.

Was able to reduce e.g. the device stack size and get a stack overflow error on the console.
