Pull request overview

This PR introduces the ebpf-extension-common submodule and wires it into the solution/projects to consume shared user-mode and kernel-mode components (notably the shared rundown API).

Changes:

• Add external/ebpf-extension-common as a git submodule and include its UM/KM projects in the solution.
• Link extension projects (and unit tests) against ebpf_extension_common_um/lib and ebpf_extension_common_km.lib, and add the shared include path.
• Replace local rundown implementation in ebpf_ext_hook_provider.c with shared rundown APIs.

The submodule URL points to a personal fork (LakshK98). For supply-chain/security and long-term reliability, it’s better to depend on the canonical upstream (or an organization-owned mirror) rather than an individual fork. Update the submodule URL to the official/maintained repository location intended for production use.
