[Clang] Fix handling of brace ellison when building deduction guides (#94889)
Fixes two issues in two ways:
1) The `braced-init-list` consisted of `initializer-list` and
`designated-initializer-list`, and thus the designated initializer is
subject to [over.match.class.deduct]p1.8, which means the brace elision
is also applicable on it for CTAD deduction guides.
2) When forming a deduction guide where the brace elision is applicable,
we should also consider the presence of braces within the initializer.
For example, given
template <class T, class U> struct X {
T t[2];
U u[3];
};
X x = {{1, 2}, 3, 4, 5};
we should establish such deduction guide AFAIU: `X(T (&&)[2], U, U, U) -> X<T, U>`.
