[Darwin][Sanitizers][CrashReporter] Adopt initializer for Crash Reporter Annotations struct (#123978)

An initializer for the Crash Reporter Annotatoins struct was added in
version 5. For the simplicity of not needing to always update the struct
in subsequent versions, this patchs checks for the initializer before
attempting to redefine the struct on its own.

Note -- we have an existing test for this that is disabled by default,
it is inherently flakey due to the nature of crash reporter. But we can
run that when making crash reporter related changes.
