NATVIS errors/warnings are not reported in cppvsdbg debugger output

Environment

• OS and version: Windows 10 Pro 22H2
• VS Code: 1.74.2
• C/C++ extension: 1.13.8

Bug Summary and Steps to Reproduce

Bug Summary:

Visual Studio provides a set of options to change NATVIS logging output, shown below:

These messages are important to identify errors in either parsing the NATVIS XML file itself, or parsing individual expressions within a given object reflected by the visualizer.

Steps to reproduce:

1. Create either a malformed NATVIS file, or annotate a type with a malformed expression
2. Observe that the entire NATVIS file is silently dropped by the debugger without any error or indications

Debugger Configurations

This occurs with the default launch configuration and a specified `visualizerFile` configuration key set.

Debugger Logs

No relevant logs were produced with the engine and trace logging enabled.

Other Extensions

No response

Additional Information

No response

Start by reproducing the malformed NATVIS file or expression with the cppvsdbg debugger, then compare the missing messages with Visual Studio's NATVIS logging behavior. Check the engine and trace logging output paths mentioned in the issue; done means NATVIS parsing and expression errors or warnings are reported instead of the file being silently dropped.
