[PATCH] libstdc++: Include range_access.h from <optional>, <stacktrace> and <valarray>

[Tomasz Kamiński]

As the range accessor all already conditionally noexcept, this implements
LWG4131 and LWG3625 (also part 4.8. section of the P3016R6). As for any
LWG issue resolutions, changes are applied as DR for oldest applicable
standards:
* <optional> (LWG4131): C++26, since optional range support
* <stacktrace> (LWG3625): C++23, since introduction

libstdc++-v3/ChangeLog:

	* include/std/optional [__cpp_lib_optional_range_support]:
	Replace <bits/stl_iterator.h> include with <bits/range_access.h>.
	* include/std/stacktrace: Likewise.
