Add ability to convert bool to int in ARM template

When you attempt to pass a bool value to the `int()` ARM template function you receive the following error

```
The template language function 'int' expects its first parameter to be one of the following types 'Integer, String'.
The provided value is of type 'Boolean'.
Please see http://aka.ms/arm-template-expressions for usage details.
```

Please add support for this. Thanks!

No repository file, test, or entry point is named. First verify whether ARM template function behavior belongs in azure-quickstart-templates or the ARM/Bicep implementation, then find the existing int() behavior and tests. Done requires an agreed boolean-conversion rule and implementation coverage for passing a bool to int().
