[Backport] Fix instances of new clang warning -Wmissing-template-arg-list-after-template-kw.

The warning requires a template argument list after using the
template keyword. Remove uses of the template keyword where we don't
want to specify template types.

See llvm/llvm-project#94194 for the upstream
clang change.
