Don't needlessly request docs from ElDoc functions
Fixes: bug#42421
Do this conservatively for now: if the ElDoc helper buffer (as
returned by eldoc--doc-buffer) is visible and showing documentation
for the very same "situation" (as computed by the the new
eldoc--request-state helper), don't request that documentation from
sources again.
Before this change, not only was that request inefficient but if the
user invoked scroll-other-window to see more of the helper buffer,
that would eventually cause it to be reformatted and unexpectedly
recentered.
Later on, when a customizable list of documentation "sinks" is offered
to the user, say, something like eldoc-display-functions, this process
must be consolidated. In those circumstances, as soon as one of those
sinks signals that it doesn't have up-to-date documentation for the
state computed by eldoc--request-state, documentation will have to be

eldoc--invoke-strategy.
