Provide property to identify when compile is only producing compilation database

[mllapps]

Describe the request

Some tools needs to know if the execution is trigger from the build button or from the database compilation or something else. With a property it would be able to give the tools the information and they can decide what is to do.

Describe the current behavior

Actualy the compilation database will trigger all prebuild recipes. This results in a problem if I add "automatic build number" to my source code project.

With my ESP32 project I use a prebuild application. This tool should run on every build step. With the actual arduino-cli version the appliaction triggers automatically on every database compilation step. So the build number increments without any click on the build button.

The problem has beend discussed here:
