use IDF_TARGET in customExtraVars if no sdkconfig

[brianignacio5]

Description

To find the current IDF_TARGET the extension reads the sdkconfig in v1.9.0 but before there was a idf.adapterTargetName configuration setting which was used to resolve IDF_TARGET. The previous logic would fail if the current project is configure for a target (say esp32) but the configuration setting is set to (say esp32c3).

Reading from sdkconfig seems like a better approach, but what happens when you want to define a IDF_TARGET but no sdkconfig exists ? For this case we still need to persist this somehow. Now we would use idf.customExtraVars configuration setting and add IDF_TARGET when running the ESP-IDF: Set Espressif Device Target command. The extension will use this value when sdkconfig IDF_TARGET value doesn't exist.

Fixes #1363

Type of change

• Bug fix (non-breaking change which fixes an issue)

Steps to test this pull request

1. Run the ESP-IDF: Set Espressif Device Target on a ESP-IDF project. This will create an sdkconfig file and build project.
2. Delete the build directory and sdkconfig file.
3. Run the ESP-IDF: Build your project command. The project should build with the target defined before instead of previously default esp32.

• Expected behaviour:

The IDF_TARGET that was set in 1 is still used when sdkconfig has been deleted for other extension commands like ESP-IDF: Build your project.

• Expected output:

The IDF_TARGET that was set in 1 is still used when sdkconfig has been deleted for other extension commands like ESP-IDF: Build your project.

How has this been tested?

Manual test by following steps above.
