* 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.
* Set empty program name to hash of instructions
ebpf_program_load_bytes now hashes the instructions and uses that for the name
instead of generating a random number.
Closes#3443
* fix signed/unsigned warning (and ensure windows helper id >= 0)
* add bcrypt.dll dependency for ebpfapi.dll
* WIP new test case for ebpf_program_load_bytes with nullptr program name
* WIP ebpf_program_load_bytes testing
* truncate SHA256 hash to 63 bytes to stay under BPF_OBJ_NAME_LEN
* remove bcrypt from release dependencies and suppress analyze warning
* PR feedback - fix comment and bpf2c include paths

Per https://stackoverflow.com/questions/13147170/attribute-always-inline-failing
the __attribute__((always_inline)) doesn't do anything unless you also
