The submdspan feature broke compatibility with clang, due to a missing
'::template type'.
libstdc++-v3/ChangeLog:
* include/std/mdspan (submdspan): Fix missing '::template'.

After this change I can compile several examples that use submdspan with
clang++ using the libstdc++ as the standard library (and I have no
examples that don't compile).
