Missing validation for condition-false `reference()` statements

The following Bicep file compiles just fine (with warnings, because of the property I made up), but fails ARM validation as the `reference(...)` function is evaluated regardless of the condition on the resource:

```bicep
var condition = false

resource test 'Microsoft.Storage/storageAccounts@2021-04-01' = if (condition) {
name: 'uniquename12982'
kind: 'StorageV2'
sku: {
name: 'Standard_LRS'
}
location: 'West US'
}

resource test2 'Microsoft.Storage/storageAccounts@2021-04-01' = if (condition) {
name: 'uniquename11298'
kind: 'StorageV2'
sku: {
name: 'Standard_LRS'
}
location: 'West US'
properties: {
someProp: test.properties.someProp
}
}
```

To fix it, change:
```bicep
someProp: test.properties.someProp
```
To:
```bicep
someProp: condition ? test.properties.someProp : null
```

This isn't made at all clear however. The template validation fails with:
```json
{
"code": "InvalidTemplate",
"message": "Deployment template validation failed: 'The template resource 'Microsoft.Storage/storageAccounts/uniquename11298' reference to 'Microsoft.Storage/storageAccounts/uniquename12982' requires an API version. Please see https://aka.ms/arm-template for usage details.'."
}
```

Start with the supplied Bicep reproduction and compare its compiler output with the ARM validation failure shown in the issue. Trace how condition-false resource references are analyzed, then add validation that clearly reports this invalid reference pattern before deployment and verify the example no longer compiles silently.
