[LLDB][NativePDB] Resolve declaration for tag types (#152579)
Tag types like stucts or enums didn't have a declaration attached to
them. The source locations are present in the IPI stream in
`LF_UDT_MOD_SRC_LINE` records:

```
   0x101F | LF_UDT_MOD_SRC_LINE [size = 18, hash = 0x1C63]
            udt = 0x1058, mod = 3, file = 1, line = 0
   0x2789 | LF_UDT_MOD_SRC_LINE [size = 18, hash = 0x1E5A]
            udt = 0x1253, mod = 35, file = 93, line = 17069
```

The file is an ID in the string table `/names`:

```
     ID | String
      1 | '\<unknown>'
     12 | 'D:\a\_work\1\s\src\ExternalAPIs\WindowsSDKInc\c\Include\10.0.22621.0\um\wingdi.h'
     93 | 'D:\a\_work\1\s\src\ExternalAPIs\WindowsSDKInc\c\Include\10.0.22621.0\um\winnt.h'
```

Here, we're not interested in `mod`. This would indicate which module
contributed the UDT.

I was looking at Rustc's PDB and found that it uses `<unknown>` for some
types, so I added a check for that.

This makes two DIA PDB shell tests to work with the native PDB plugin.
