platform_build_soong/android/env.go
Lukacs T. Berki 7d613bfe2c Make it possible to debug soong_ui.
This works by setting the SOONG_UI_DELVE= environment variable to the
port on which soong_ui should accept a Delve connection on.

This is achieved by reusing the Delve execution logic between soong_ui
and soong_build.

Test: Manual.
