call hierarchy doesn't show thread creations using the function pointer

Environment

• OS and Version: Windows_NT x64 10.0.19045
• VS Code Version: 1.94.0
• C/C++ Extension Version: 1.22.11
• If using SSH remote, specify OS of remote machine: Ubuntu 20.04.6 LTS

Bug Summary and Steps to Reproduce

Bug Summary:
When you look for call hierarchy of a function, it doesn't list the references where it is called as function pointer, for example thread creation. This is useful, else we have to figure out the rest of the hierarchy using search function.

Steps to reproduce:

1. Go to '...' function definition or declaration
2. Click on '....' right click and select call hierarchy
3. Scroll down to '....'
4. See error

Expected behavior:

Additional context

No response

No repository files or tests are named. Start by reproducing the call hierarchy from a C or C++ function used as a function pointer for thread creation, then trace the call-hierarchy implementation in the extension. Done means references reached through the function pointer appear in the hierarchy, with a regression test covering the case.
