[Lldb-commits] [lldb] [lldb] Transfer some environment variables into the tests on Windows build host (PR #115613)

[Dmitry Vasilyev via lldb-commits]

https://github.com/slydiman created https://github.com/llvm/llvm-project/pull/115613

Some API tests (compiler calls) create a lot of garbage and cause unexpected behavior in case of Windows host and Linux target, e.g.
```
lldb/test/API/commands/process/attach/%SystemDrive%/
lldb/test/API/functionalities/deleted-executable/%SystemDrive%/
lldb/test/API/functionalities/exec/%SystemDrive%/
lldb/test/API/functionalities/load_unload/%SystemDrive%/
lldb/test/API/functionalities/target-new-solib-notifications/%SystemDrive%/
lldb/test/API/functionalities/thread/create_after_attach/%SystemDrive%/
```
It can be fixed by transfer some standard Windows environment variables into API tests.
