tools: ynl: move python code to separate sub-directory
Move python code to a separate directory so it can be
packaged as a python module. Updates existing references
in selftests and docs.
Also rename ynl-gen-[c|rst] to ynl_gen_[c|rst], avoid
dashes as these prevent easy imports for entrypoints.

doc: net: napi: Update documentation for napi_schedule_irqoff
Since commit 8380c81d5c ("net: Treat __napi_schedule_irqoff() as
__napi_schedule() on PREEMPT_RT"), napi_schedule_irqoff will do the
right thing if IRQs are threaded. Therefore, there is no need to use
IRQF_NO_THREAD.
