chore(sdk): bump llama.cpp to b10019 (#1182)

Retarget the vendored llama.cpp submodule from b9775 to b10019.

Upstream #24954 dropped the v68/v69 HTP skel targets, so the
install-htp-skels wrapper in plugins/llama_cpp/CMakeLists.txt no longer
has htp-v68/htp-v69 to depend on. Drop both from the skel version lists
(build, install, and pkg-layout copy) to match the new upstream set
(v73/v75/v79/v81).

The llama-hexagon-release-sessions patch still applies cleanly. Verified
end-to-end on qcs (Windows arm64 Snapdragon): SDK configures, builds, and
installs; geniex.dll and the v73+ skels land in pkg-geniex.
