Add path to MSVC binaries to PATH for launch/debug

### Brief Issue Summary

There are some DLL files MSVC may link to, but are not included in PATH. This especially affects the AddressSanitizer; the needed runtime DLLs lie with the compiler binaries.

In my case, the needed files are located at `C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.29.30037\bin\Hostx64\x64`. Depending on the selected toolkit and the VS version, hardcoding this path makes no sense.

### Expected:

1. Create quick start project with executable binary
2. Add `set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} /Oy- /fsanitize=address")` to CMakeLists.txt
3. Build project
4. Run resulting binary using "run" or "debug" button in the bottom bar

Note: A solution in which I somehow pass the compiler path into the launch configuration would be fine for me. But for that, I need to know a substitution variable to use for that.

### Apparent Behavior:

The compiled binary exits with exit code -1073741515 (0xc0000135). (seen in debug output)
I did some research and this exit code is usually caused by missing DLL files.

### Platform and Versions

- **Operating System**: Windows 10
- **CMake Version**: 3.20.21032501-MSVC_2
- **VSCode Version**: 1.57.1
- **CMake Tools Extension Version**: 1.7.,3
- **Compiler/Toolchain**: Visual Studio Build Tools 2019 16.10.2+857e5a733; MSVC 19.29.30038.1

Start by reproducing the Windows 10 quick-start project with the MSVC AddressSanitizer flags and inspect how CMake Tools constructs the launch and debug environment. Done means the MSVC compiler-binary directory is located without a hardcoded versioned path and the resulting executable launches or debugs without the missing-DLL error.
