[Feature Request]: Kconfig GUI should show when a value is forced by another config option (VSC-1751)

[jrahlf]

Is your feature request related to a problem? Please describe.
Sometimes you change a value, press save and then realize, that the config option automatically reverted to its previous value or state.

Describe the solution you'd like
The GUI should indicate, when a value is forced by another config value. It should show which specific config option is forcing the value.
Maybe even disable the item so that it cannot be changed, but still show the relevant information.

Could you provide an example to reproduce this issue.

Know that if the Kconfig value is dependent on other value, this could happen for many settings.

You can see the values changes when you change one value in the Output -> ESP-IDF while using the SDK Configuration Editor.

Example: esp32s3 project (IDF 5.4). "Elliptic Cuve Ciphers" is selected and so is "Elliptic Curve Diffie-Hellman (ECDH)".

1. De-select ECDH
2. Select and de-select any other value
3. ECDH is automatically selected again

The output log does not indicate that the ECDH value was automatically changed. Even if it did, it would be much better to have such information beforehand in the editor. See the output log below, where I first deselected ECDH and then toggled "JPAKE". Currently I have to grep through the entire project to understand where such forced values are coming from.

{"version": 2, "set": { "MBEDTLS_ECDH_C": false }}
Set MBEDTLS_ECDH_C
{"version": 2, "values": {}, "ranges": {}, "visible": {}}

{"version": 2, "set": { "MBEDTLS_ECJPAKE_C": true }}
Set MBEDTLS_ECJPAKE_C
{"version": 2, "values": {"MBEDTLS_KEY_EXCHANGE_ECJPAKE": false, "MBEDTLS_ECJPAKE_C": true}, "ranges": {}, "visible": {"MBEDTLS_KEY_EXCHANGE_ECJPAKE": true}}


{"version": 2, "set": { "MBEDTLS_ECJPAKE_C": false }}
Set MBEDTLS_ECJPAKE_C
{"version": 2, "values": {"MBEDTLS_ECJPAKE_C": false}, "ranges": {}, "visible": {"MBEDTLS_KEY_EXCHANGE_ECJPAKE": false}}

Thank you for your response.

The question is then, how can we show this in the SDK Configuration Editor? Notice how when you change one value, multiple values change due to dependency to this kconfig setting. We could highlight modified settings with yellow to mark that the settings were changed indirectly.
