Build of esp32-s2-kaluga-1/examples/lcd fails in VS Code ESP-IDF Extension - No such file or directory #include "soc/system_reg.h"

[georgik]

How to simulate:

• clone esp-dev-kits
• open esp32-s2-kaluga-1/examples/lcd
• CTRL+Shift+P, select ESP-IDF: Build, flash...
• the build fails:

  esp-dev-kits/esp32-s2-kaluga-1/components/lcd/lcd.c:22:10: fatal error: soc/system_reg.h: No such file or directory
  #include "soc/system_reg.h"
        ^~~~~~~~~~~~~~~~~~
  compilation terminated.

Root cause:

• VS Code ESP-IDF Extension does not select esp32s2 target as default. The build from command line ESP-IDF works and esp32s2 is correctly set

Workaround:

• CTRL+Shift+P, select ESP-IDF: Set Espressif device target, select ESP32-S2
• run build

Expected behavior: VS Code ESP-IDF Extension picks the target from the project, so that user do not need to set the target manually

Currently the extension has a configuration setting idf.adapterTargetName with esp32 as default value which set IDF_TARGET environment variable for the build task.

I'll make a fix to get the IDF_TARGET from sdkconfig on selected workspace folder change.

Tested with new version of VS Code. The chip is selected correctly and it's also visible in the bottom bar. Thank you.
