ebpfapi.dll should not depend on usersim.dll

[Alan-Jowett]

Non-test programs using eBPF for Windows should not pull in usersim.dll

[dthaler]

See issue #2677. Currently usersim.dll includes some things that could be user-mode runtime related, and those parts would be needed for some non-test components. I was planning on handling things like export_program_info.exe as part of that work. For example, a couple places in the code have:

TODO(#2677): export_program_info.exe temporarily requires usersim.dll

We could factor usersim.dll into two binaries in the same repo or more likely move some to another repo like cxplat.

If ebpfapi.dll depends on usersim.dll, it will require one more user mode binary to be installed. It can probably also increase load time.

framework.h already has this:

// TODO(#2677): remove the following include, which should be private to usersim.dll.
#include "..\..\..\external\usersim\src\framework.h"

which I think is what this issue needs to do.
