libstdc++: Don't use std::__is_scalar in std::valarray initialization [PR115497]

This removes the use of the std::__is_scalar trait from <valarray>,
where it can be replaced by __is_trivial. It's used to decide whether we
can use memset to value-initialize valarray elements, but memset is
suitable for any trivial types, because value-initializing them is
equivalent to filling them with zeros.

This is another step towards removing the class templates in
<bits/cpp_type_traits.h> that conflict with Clang built-in names.

libstdc++-v3/ChangeLog:

	PR libstdc++/115497
	* include/bits/valarray_array.h (__valarray_default_construct):
	Use __is_trivial(_Tp). instead of __is_scalar<_Tp>.
