Compatibility issues with .NET AoT-compiled binaries

Nobody has claimed this yet.

### Description

Using the now-latest commit d4d856767d89faf6e9ebae069671a9151c2c7f31, feeding capa a .NET 8.0 Ahead-of-Time compiled binary causes multiple issues to crop up.

- For the standalone version, vtrace complains about `Unhandled Variant Type: 21`, but the standalone version is still able to finish the analysis and display the results

```
Exception ignored on calling ctypes callback function: >

```

- For the IDA plugin (IDA 8.3), an issue with ida_bytes.bin_search shows up,

```

### Steps to Reproduce

1. Create a .NET 8.0 project (`dotnet new console`)
2. Compile the project as AoT (`dotnet publish -c release -r win-x64 /p:PublishAot=true /p:PublishSingleFile=false`)
3. Feed the compiled project to capa as either the standalone or IDA version
4. Both feature the errors above

**Expected behavior:**

Finish the analysis without errors

**Actual behavior:**

Errors show up

### Versions

- capa 7.4.0 (d4d856767d89faf6e9ebae069671a9151c2c7f31)
- Python 3.10
- Windows 11 (Build 22635.4371)
- IDA 8.3

### Additional Information

Reproduce the issue with the listed .NET 8 AoT publish command, using both the standalone and IDA versions. Start with vtrace.platforms.win32.py around typeEnumCallback and symGetTypeValue, then capa/features/extractors/ida/helpers.py around find_byte_sequence and its ida_bytes.bin_search call. Done means both integrations analyze the binary without the reported errors.
