[API Proposal]: Optionally add CallerLineNumber and CallerFilePath to logging source generator

### Background and motivation

When a generated logger method is called from multiple places, it can help debugging if we had the call site information. The compiler already knows how to emit those automatically using the `CallerLineNumber` and `CallerFilePath` attributes. By generating additional overloads tagged with `OverloadResolutionPriority`, we can easily get this information into each log call.

This can be an optional behavior enabled using an MSBuild property or an assembly/class attribute.

### API Proposal

User code:

```csharp
[EmitCallSiteInformation]
static partial class LoggerExtensions
{
public static partial void LogMethod(ILogger logger);
}
```

Generated code:

```csharp
static partial class LoggerExtensions

{
public static partial void LogMethod(ILogger logger) => LogMethod(logger, default, default);

[OverloadResolutionPriority(1)]
public static void LogMethod(ILogger logger, [CallerFilePath] string? filePath = default, [CallerLineNumber] int lineNumber = default) ...
}
```
