[C] Do not diagnose flexible array members with -Wdefault-const-init-field-unsafe (#140578)

This addresses post-commit review feedback from someone who discovered
that we diagnosed code like the following:
```
  struct S {
    int len;
    const char fam[];
  } s;
```
despite it being invalid to initialize the flexible array member.

Note, this applies to flexible array members and zero-sized arrays at
the end of a structure (an old-style flexible array member), but it does
not apply to one-sized arrays at the end of a structure because those do
occupy storage that can be initialized.
