Etienne PerotandgVisor bot 056a85f39d Mark all ABI structs with structs.HostLayout; verify this remains true.
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.
