QtCreator replaces PATH environment variable removing user settings

Howto reproduce

• have Kit for visual studio 2022 setup
• start "x64 Native Tools Command Prompt for VS 2022" to have CMD shell.
• extend PATH by command line:
  set PATH=FOOBAR;%PATH%
• start QtCreator from this shell
• open a project
• Check PATH in Project/Build/Build Environment

Result:

"FOOBAR" is not part of the PATH anymore.

Should be:

"FOOBAR" ist still part of the PATH. PATH should not be changed.

Remark 1:

If CMD is just a "normal" shell and not a "x64 Native Tools ..." shell and PATH was extended with FOOBAR than this extension is kept.

So, switching toolchains in Projekt Build&Run seems to "outsmart" the user setup, if CMD is already a Visual Studio CMD shell.

Remark 2:

QtCreator 8 kept the extension of PATH (but duplicated the PATH parts that are relevant for the Visual Studio toolchain).
