cargo-generate: add perf_event 
This adds `perf_event` program type as a template entry.
The new entry comes with a skeleton example which register
scheduled events on each CPU at 1 HZ, triggered by the kernel
(based on clock ticks). The corresponding BPF logic logs each
event, and can identify kernel tasks from userland processes.

Michal Rostecki 379b23b1b4 ebpf: Stop using `unsafe` for the whole function 
Users should opt in into `unsafe` when performing particular unsafe
actions (accesing raw pointers, interacting with maps etc.), but
assuming that the whole eBPF program code is unsafe is quite an
exaggeration.

Michal Rostecki 0c4b89b497 ebpf: Change `static mut` to `static` in map declaration 
Maps are using UnsafeCell for interior mutability, therefore `static
mut` is not needed anymore.

Michal Rostecki 1ecc829b4f classifier: Use the new `TcContext` struct 
That new context type exposes `data` and `data_end` fields for direct
access to the packet payload.

Dave Tucker d98d90be7a Generate Skeleton Programs for all program types 
User may specify a program_type by prompt or CLI flag.
We then generate skeleton code to the ebpf program for a noop program of
that type.

Requires cargo-generate@main
