* 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.

* Add interface luid to bpf_sock_addr and bpf_sock_ops
And also add compartment id to bpf_sock_ops for consistency with
bpf_sock_addr, so that it is available to eBPF programs.
Signed-off-by: Dave Thaler <dthaler@microsoft.com>
* Expose interface luid and compartment id to sock_ops and sock_addr hooks
* compartment_id was exposed to sock_addr but not sock_ops
* interface_luid was not exposed to either
Exposing the interface_luid should be a performant way to compensate for
lack of scope_id in the hooks, since the interface luid is available
in the WFP callout, and is more specific than a scope id (so a scope id
can always be looked up from the interface luid in the future if
needed).
