Provide public API for ResourceContentHash annotation generation (#5402)

Provides `generateResourceContentHashAnnotation` property for
`generateResourceAccessorsFor*` tasks that defines whether to generate
`@ResourceContentHash` annotation for resource accessors.
The property can be set the following way:

```
tasks.configureEach {  
    if (this is org.jetbrains.compose.resources.ResourceAccessorsConfiguration) {
        generateResourceContentHashAnnotation.set(true)
    }
}    
```

## Release Notes
### Features - Multiple Platforms
- Provide public API for `@ResourceContentHash` annotation generation
