Michael Buch b650764b16 [lldb][test] Add test for completing ObjCObjectType (#95405) ...

This is a minimal reproducer for a crash where we would try to call
`DumpTypeDescription` on an incomplete type. This crash surfaced as part
of an NFC refactor of some of the logic in `GetCompleteQualType`:
```
(lldb) expr -l objc -- *(id)0x1234
Stack dump:
0.      Program arguments: ./bin/lldb a.out -o "b main" -o run -o "expr -l objc -- *(id)0x1234"
Stack dump without symbol names (ensure you have llvm-symbolizer in your PATH or set the environment var LLVM_SYMBOLIZER_PATH to point to it):
0  lldb                     0x0000000102ec768c llvm::sys::PrintStackTrace(llvm::raw_ostream&, int) + 56
1  lldb                     0x0000000102ec6010 llvm::sys::RunSignalHandlers() + 112
