Add wrappers for 'zig c++' to work around clangd

+## clangd
+
+To get [clangd](https://clangd.llvm.org/) to work you need to first enable generation of `compile_commands.json`:
+
+```sh
+cmake -B build -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
+```
+
+Additionally you need to pass pass the following arguments to `clangd`:
+
+```json
+"clangd.arguments": [
+    "--log=verbose",
+    "--query-driver=*/clang-cl.exe,*/zig-cc.*,*/zig-c++.*,*/em++.bat,*/emcc.bat,*/em++,*/emcc",
+]
+```
+
+Without these arguments `clangd` will not query the driver (`zig c++`) and the include paths will not be resolved correctly.
