  [clang] Fix assertion failure when initializing union with FAM (#77298)

When initializing a union that constrain a struct with a flexible array
member, and the initializer list is empty, we currently trigger an
assertion failure. This happens because getFlexibleArrayInitChars()
assumes that the initializer list is non-empty.

Fixes https://github.com/llvm/llvm-project/issues/77085.
