  [clang][bytecode] Support partial initializers for CXXNewExprs (#126494)

For `new A[N]{1,2,3}`, we need to allocate N elements of type A, and
initialize the first three with the given InitListExpr elements.
However, if N is larger than 3, we need to initialize the remaining
elements with the InitListExpr array filler.

Similarly, for `new A[N];`, we need to initilize all fields with the
constructor of A. The initializer type is a CXXConstructExpr of
IncompleteArrayType in this case, which we can't generally handle.
