Add environment variable overrides for stack, heap
If you define a runtime, you can call `stack_size_env_override` to
define an optional environment variable checked by the runtime builder.
Same goes for the heap. A user can set these environment variables to
override the runtime's stack / heap size. You can use this package's
examples to try it out; see the updated build script.
There's no default environment variable for either memory region. The
package that defines the runtime needs to opt-in to this feature.
