libstdc++: Reduce header dependencies of <algorithm> in C++20 [PR 92546]

Browse Source 
The <bits/ranges_algobase.h> header doesn't need the stream and
streambuf iterators, so don't include the whole of <iterator>.

libstdc++-v3/ChangeLog:

	PR libstdc++/92546
	* include/bits/ranges_algobase.h: Replace <iterator> with a
	subset of the headers it includes.
