Backport of #109763 to release/9.0-staging

/cc @elinor-fung @alexrp

Customer Impact

  • Customer reported
  • Found internally

hostfxr.h provided for customers doing custom hosting is not valid C, so consumers in C cannot not use the latest version.

Regression

  • Yes
  • No

Regressed in 9.0 with #101451.

Testing

Manual.

Risk

Low. The change just adds the struct keyword for a function parameter such that the header is valid C again.

sounded like there might be one or two other headers that could benefit from similar protection?

Absolutely! The three documented headers: https://learn.microsoft.com/en-us/dotnet/core/tutorials/netcore-hosting

#include <nethost.h>
#include <coreclr_delegates.h>
#include <hostfxr.h>

I'll fix it in main.
