* Fix sample project dependencies
Bug was that if you cleaned everything and then tried to build just the
sample_ebpf_ext project, building would fail. A race condition also
existed when trying to build everything in that if
execution_context_kernel wasn't't done building by the
time sample_ebpf_ext was ready to link, the build would also fail.

* Create an install script rather than having to manually do lots
of steps
* 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
are part of Windows, unlike vcruntime debug DLLs

* Simplify names of some ebpf_result codes
* Remove _ERROR_ for consistency
* Combine EBPF_INVALID_HANDLE and EBPF_INVALID_OBJECT
* Rename EBPF_ERROR_NOT_FOUND to EBPF_KEY_NOT_FOUND for consistency with the associated description.

key, to use a different appropriate result, so the description stays correct.
