  [LLDB][NativePDB] Implement `FindNamespace` (#151950)

`FindNamespace` was not implemented for `SymbolFileNativePDB`. Without
it, it wasn't possible to lookup items through namespaces when
evaluating expressions.

This is mostly the same as in
[SymbolFilePDB](https://github.com/llvm/llvm-project/blob/f1eb869bae2ab86726ee3a5a5c7980d5b2acbd5d/lldb/source/Plugins/SymbolFile/PDB/SymbolFilePDB.cpp#L1664-L1696)
as well as
[PDBAstParser](https://github.com/llvm/llvm-project/blob/f1eb869bae2ab86726ee3a5a5c7980d5b2acbd5d/lldb/source/Plugins/SymbolFile/PDB/PDBASTParser.cpp#L1126-L1150):
The AST parser/builder saves the created namespaces in a map to lookup
when a namespace is requested.

This is working towards making
[Shell/SymbolFile/PDB/expressions.test](https://github.com/llvm/llvm-project/blob/f1eb869bae2ab86726ee3a5a5c7980d5b2acbd5d/lldb/test/Shell/SymbolFile/PDB/expressions.test)
pass with the native PDB plugin.
