Use structs.HostLayout in all Platform specific structs
Why is this needed?
In Go 1.23, a new package and type called structs.HostLayout was added in https://github.com/golang/go/issues/66408. Adding this field to a struct instructs the compiler to guarantee the struct matches the C ABI.
We currently, rely on the fact that Go's current struct layout matches the C ABI. The following is an incomplete list of structs that must match C ABI.
objc_super
G
ThreadStart
pthread_mutex_t
pthread_cond_t
As well as all the one's in struct_test.go, objc_runtime_darwin_test.go and in the examples/window platform files
This is not urgent as there is no current plan to change Go's struct layout
