* Move C++ hashing lib from tests/libs/util/ to libs/shared/
This puts hash.cpp/hash.h in a more central location for use by other project files.

ebpf_program_load_bytes now hashes the instructions and uses that for the name
instead of generating a random number.

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.
