Source Server support is missing

Environment

• OS and version: Windows
• VS Code: 1.93
• C/C++ extension: 1.21.6
• OS and version of remote machine (if applicable): N/A
• GDB / LLDB version: N/A

Bug Summary and Steps to Reproduce

Bug Summary:
It is possible to put source-server information in the pdb files. (See https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/the-srcsrv-ini-file)
With this, you can add a link to a git/svn/... server and explain how to get the source code from it.
If you debug in visual studio, it extracts this information from the PDB and asks if you trust the command to download the sources. If you do, you will see the sources as they were stored in the git/svn/... server for that specific revision.

Steps to reproduce:

1. Create a binary with pdbs and source server info
2. Run the binary
3. Make dump file from it (taskmanager)
4. Open the dump file in VS Code
5. See that the sources are not loaded.

Start with the cppvsdbg dump-file flow and investigate how PDB source information is currently handled. Use the provided Windows dump reproduction and source-server documentation as the first checks. Done means opening the dump can retrieve the revision-specific sources from the configured server, with an appropriate trust prompt.
