Implement bpf_task_work_schedule_* with an implicit bpf_prog_aux
argument, and remove corresponding _impl funcs from the kernel.
Update special kfunc checks in the verifier accordingly.
Update the selftests to use the new API with implicit argument.

bpf_task_work_schedule_resume() and bpf_task_work_schedule_signal() have
been renamed in bpf tree to bpf_task_work_schedule_resume_impl() and
bpf_task_work_schedule_signal_impl() accordingly.
There are few uses of these kfuncs in selftests that are not in bpf
tree, so that when we port [1] into bpf-next, those BPF programs will
not compile.
This patch aligns those remaining callsites with the kfunc renaming.
It should go on top of [1] when applying on bpf-next.

file_reader/on_open_expect_fault intermittently fails when test_progs
runs tests in parallel, because it expects a page fault on first read.
Another file_reader test running concurrently may have already pulled
the same pages into the page cache, eliminating the fault and causing a
spurious failure.
Make file_reader/on_open_expect_fault read from a file region that does
not overlap with other file_reader tests, so the initial access still
faults even under parallel execution.

Introducing selftests for validating file-backed dynptr works as
expected.
* validate implementation supports dynptr slice and read operations
* validate destructors should be paired with initializers
* validate sleepable progs can page in.
