`LOCALE_NAME_USER_DEFAULT` API is missing

## Actual behavior

PInvoke001: Method, type or constant "LOCALE_NAME_USER_DEFAULT" not found

## Expected behavior

I get a desired API generaed as it is defined in official docs: https://learn.microsoft.com/en-us/windows/win32/intl/locale-name-constants. Note that other APIs from that page generate without errors

## Repro steps

1. `NativeMethods.txt` content:
```
LOCALE_NAME_INVARIANT
LOCALE_NAME_MAX_LENGTH
LOCALE_NAME_SYSTEM_DEFAULT
LOCALE_NAME_USER_DEFAULT
```

### Context

- CsWin32 version: `0.3.183`
- Win32Metadata version (if explicitly set by project): Not explicitly set
- Target Framework: `net10.0`
- `LangVersion` (if explicitly set by project): Not explicitly set

Start with the NativeMethods.txt reproduction and compare the four locale-name constants against the official Windows documentation. Trace how these constants are represented and generated in win32metadata and CsWin32. Done means LOCALE_NAME_USER_DEFAULT generates successfully alongside the other listed constants.
