mach: require a 'pub const App' to be exposed

Browse source 
This requires apps expose a `pub const App` from their `main.zig`, effectively adopting
the high-level/low-level application API outlined in hexops/mach#349

If `pub const App` does not exist, a clear compiler error is produced:

```
./src/platform/common.zig:5:9: error: expected e.g. `pub const App = mach.App(modules, init)' (App definition missing in your main Zig file)
        @compileError("expected e.g. `pub const App = mach.App(modules, init)' (App definition missing in your main Zig file)");
        ^
./src/platform/native.zig:13:28: note: called from here
    common.checkApplication(app_pkg);
                           ^
./src/platform/native.zig:12:10: note: called from here
comptime {
         ^
./src/platform/native.zig:15:20: error: container '.app' has no member called 'App'
const App = app_pkg.App;
                   ^
```
