Moves Windows platform files into the internal repo.
Also adds ebpf_windows.h file to centralize defines that were previously duplicated in at least three places in this repo, and one ,more previously in the windows branch of prevail, now all unified.

- adds support to receive opcode based commands from usermode for load/unload/attach/detach
- parses layerdata from wfp classify
- passes in xdp_md like context to usermode code from the classify context
- modified test tool to test these changes
- adds a droppacket.c code with instructions to illustrate xdp and ctx based evaluation for dosp.

This POC proves the Prevail verifier can run in an enclave.
Note that this POC also does the ELF parser in an enclave too,
just to prove that the entire Prevail code can run in an enclave,
even though we don't want to do ELF parsing in an enclave.

Still don't have an API to call, but add in parser logic for command arguments.
(And fix ordering of tags where needed, since required tags have to come before optional ones.)

Code is organized such that it points to the elf headers from the ebpf-verifier submodule. It uses non gpl contructs to grab a vector of ebpf instructions given a file path for an elf file.

pass in code from um via ioctl and execute in kernel.
Basic version to demonstrate that we can push code from um into kernel and get it to run there, all using public APIs.
