Investigate porting pdb support to Microsoft's rust crate

[CouleeApps]

Microsoft just published https://github.com/microsoft/pdb-rs which seems to have more complete support for PDB files. We should look into swapping out our use of the now-rather-defunct pdb crate for this crate instead. It doesn't seem like these are based on the same codebase, so porting effort seems nontrivial. Will need further investigation.

Considering the effort involved here I think it might be worth considering doing alongside #6487 not necessarily required however both will be touching a considerable amount of code in the pdb plugin.

Do they support PDB 2.0?
