You can debug programs created by clang with gdb (which you already installed).

Clang has its own debugger (called lldb). It's packaged separately and
you can install it with

  sudo apt-get install lldb

(You can also debug programs created with g++ with lldb. Such is the
power of open standards)

However, I would recommend checking out Visual Studio Code, which can
do remote development (including debugging) on WSL (vscode runs on
Windows, compilers and debuggers run on WSL).
