Other projects can now consume ebpf-for-windows in binary form,
using either nuget or MSI install. We no longer need to build
ebpf-for-windows both ways, so removing the cmake build to free
up build resources and reduce the development cost of maintaining
both msbuild and cmake builds.

* Fix code analysis annotations for _In_ and _In_opt_ parameters,
add const where appropriate or change to _Inout_ where appropriate.
The following regex expressions were used to find the problems:
Find _In_ or _In_opt_ that are not const and are not followed by _Post_invalid_ or _Frees_ptr_ or _Post_ptr_invalid_:
```_In_[ ]+(?!.*(const|_Post_invalid_|_Frees_ptr_|_Post_ptr_invalid_))```
```_In_opt_[ ]+(?!.*(const|_Post_invalid_|_Frees_ptr_|_Post_ptr_invalid_))```
Some of the _In_ and _In_opt_ parameters are not const due to required compatibility with the Windows API.
Pointers to functions are const by definition, so the const qualifier is not required.

* Make Debug build use vcruntime as static libs to avoid adding
another prerequisite on a machine before installing eBPF. This
isn't required for Release builds as vcruntime release DLLs
