Jonathan Wakely ac73c944ea libstdc++: Reduce header dependencies from PSTL headers [PR92546] 
This avoids including the whole of <functional> in <algorithm>, as the
<pstl/glue_algorithm_defs.h> header only actually needs std::pair.

This also avoids including <iterator> in <pstl/utils.h>, which only
needs <type_traits>, std::bad_alloc, and std::terminate (which can be
repalced with std::__terminate). This matters less, because
<pstl/utils.h> is only included by the <pstl/*_impl.h> headers and they
all use <iterator> anyway, and are only included by <execution>.

libstdc++-v3/ChangeLog:

	PR libstdc++/92546
	* include/pstl/glue_algorithm_defs.h: Replace <functional> with
	<bits/stl_pair.h>.
	* include/pstl/utils.h: Replace <iterator> with <type_traits>.
	(__pstl::__internal::__except_handler): Use std::__terminate
	instead of std::terminate.
