resolves: #504
this PR implements additional eBPF helpers funcs for
get_sm_id,get_warp_id, andget_lane_idand adds a new GPU example that demonstrates how to trace thread (sm/warp/lane) scheduling using these eBPF helpers.Testing
tested locally on RTX 3090 (steps to run the example documented in the README):
sidenote: during development with the 3090, i had to explicitly set the env var
BPFTIME_SM_ARCH=sm_86to be able to run bpftime (see: #516), i left this detail out of the README since it looks like SM_ARCH auto-detect will be handled by #524
