libstdc++: Silence warning in mdspan.
Splitting the tests for submdspan triggered a compiler warning. This
commit changes the implementation of __dynamic_extents. In particular,
how the span is created. Functionally, the two are equivalent.
libstdc++-v3/ChangeLog:
* include/std/mdspan (_ExtentsStorage::_M_dynamic_extents):
Create span from pointer + size, not begin and end iterators.
