libstdc++: Implement __mdspan::__size.

The current code uses __mdspan::__fwd_prod(__exts, __rank) to express
computing the size of an extent. This commit adds an function __mdspan::
__size(__exts) to express the idea more directly.

libstdc++-v3/ChangeLog:

* include/std/mdspan (__mdspan::__size): New function.
