This change marks all ABI-related structs with `structs.HostLayout`, which was introduced in Go 1.23: https://pkg.go.dev/[email protected]#HostLayout This is intended to force the Go compiler to preserve the layout of the struct, removing it from the liberty of reordering fields as it sees fit. Adds a check automatically generated by our `go_library` rule wrapper which verifies this recursively for all exported structs in a package. Fixes issue #10693. PiperOrigin-RevId: 860238103
