refactor(examples): improve the esp32-std-demo (#157)

- chore(sdkdefaults): adjust settings and move to workspace root
  - Increase the stack size to 16kb
  - Enable tracing for stack overflows
  - Copy the file to workspace root (to respect it always)

- chore(profiles): enable profiles on workspace

This is needed for enabling the optimizations for the demos
Plus I don't think it would hurt

- chore(esp32-std-demo): bump ESP-IDF version to v5.4

- chore(esp32-std-demo): remove unnecessary features of esp-idf-svc dependency

- chore(esp32-std-demo): fix the link to the repository

- refactor(esp32-std-demo): drop the mousefood- prefix
