Capitalize in various places where appropriate

These are mostly acronyms (CPUs; ZILs) but also proper nouns such as
"Unix" and "Unicode" which should also be capitalized.

Make use of "i.e." (id est) consistent

This is the most common way it is written throughout the manpages, but
there are a few cases where it is written slightly differently.

spl-proc: remove old taskq stats

These had minimal useful information for the admin, didn't work properly
in some places, and knew far too much about taskq internals.

With the new stats available, these should never be needed anymore.

Linux: Cleanup taskq threads spawn/exit

This changes taskq_thread_should_stop() to limit maximum exit rate
for idle threads to one per 5 seconds.  I believe the previous one
was broken, not allowing any thread exits for tasks arriving more
than one at a time and so completing while others are running.

Also while there:
 - Remove taskq_thread_spawn() calls on task allocation errors.
 - Remove extra taskq_thread_should_stop() call.

Closes #15507 

Add a delay to tearing down threads.

It's been observed that in certain workloads (zvol-related being a
big one), ZFS will end up spending a large amount of time spinning
up taskqs only to tear them down again almost immediately, then
spin them up again...

I noticed this when I looked at what my mostly-idle system was doing
and wondered how on earth taskq creation/destroy was a bunch of time...

So I added a configurable delay to avoid it tearing down tasks the
first time it notices them idle, and the total number of threads at
steady state went up, but the amount of time being burned just
tearing down/turning up new ones almost vanished.
