Update architecture diagram to remove or de-emphasize interpreter

[dthaler]

Describe the bug

Currently the main diagram at https://github.com/microsoft/ebpf-for-windows shows the interpreter prominently.
This apparently leads some to believe it's a key part of the Windows implementation, and a news article this week even stated:
"Like the Linux eBPF, Windows eBPF will offer a sandbox to execute small programs within the kernel itself, using an enclaved in-kernel interpreter to execute eBPF bytecode, once the code is verified."

In my LinkedIn post, I corrected this and pointed to Alan's blog article Towards debuggability and secure deployments of eBPF programs on Windows but the fact remains that the diagram is misleading and should be updated now. Importantly the native mode isn't even depicted or mentioned on the main page and should be.

Steps taken to reproduce bug
