operator/(duration, duration) has wrong return type

[mtnpke]

operator/ with two durations as arguments is implemented to return a duration:

EASTL/include/EASTL/chrono.h

Lines 337 to 343 in 7fadbf0

	template <typename Rep1, typename Period1, typename Rep2, typename Period2>
	typename eastl::common_type<duration<Rep1, Period1>, duration<Rep2, Period2>>::type EASTL_FORCE_INLINE
	operator/(const duration<Rep1, Period1>& lhs, const duration<Rep2, Period2>& rhs)
	{
	typedef typename eastl::common_type<duration<Rep1, Period1>, duration<Rep2, Period2>>::type common_duration_t;
	return common_duration_t(common_duration_t(lhs).count() / common_duration_t(rhs).count());
	}

This is wrong; see https://en.cppreference.com/w/cpp/chrono/duration/operator_arith4 (6) - "Note that the return value of this operator is not a duration."

Divison of two durations should return a dimensionless number and not a duration.
