  [LLDB][NativePDB] Look for PDBs in `target.debug-file-search-paths` (#169719)

Similar to DWARF's DWO, we should look for PDBs in
`target.debug-file-search-paths` if the PDB isn't at the original
location or next to the executable.

With this PR, the search order is as follows:

1. PDB path specified in the PE/COFF file
2. Next to the executable
3. In `target.debug-file-search-paths`

This roughly matches [the order Visual Studio
uses](https://learn.microsoft.com/en-us/visualstudio/debugger/specify-symbol-dot-pdb-and-source-files-in-the-visual-studio-debugger?view=vs-2022#where-the-debugger-looks-for-symbols),
except that we don't have a project folder and don't support symbol
servers.

Closes #125355 (though I think this is already fixed in the native
plugin).
