sched/fair: Remove sched_trace_*() helper functions
We no longer need them as we can use DWARF debug info or BTF + pahole to
re-generate the required structs to compile against them for a given
kernel.
This moves the burden of maintaining these helper functions to the
module.
https://github.com/qais-yousef/sched_tp
Note that pahole v1.15 is required at least for using DWARF. And for BTF
v1.23 which is not yet released will be required. There's alignment
problem that will lead to crashes in earlier versions when used with
BTF.
We should have enough infrastructure to make these helper functions now
obsolete, so remove them.
[Rewrote commit message to reflect the new alternative]
