Implement connect redirect and bind redirect.

(This issue is created from some of the tasks in #786 that was incorrectly associated with the wrong program type)

### Describe the feature you'd like supported

An eBPF program of type BPF_PROG_TYPE_SOCK_ADDR program type attached to `BPF_CGROUP_INETx_CONNECT` can be used to redirect or rebind a connection at connect time.

Example: https://github.com/torvalds/linux/blob/fc02cb2b37fe2cbf1d3334b9f0f0eab9431766c4/tools/testing/selftests/bpf/progs/connect_force_port4.c

```
SEC("cgroup/connect4")
int connect4(struct bpf_sock_addr *ctx)
{
struct sockaddr_in sa = {};
struct svc_addr *orig;

/* Force local address to 127.0.0.1:22222. */
sa.sin_family = AF_INET;
sa.sin_port = bpf_htons(22222);
sa.sin_addr.s_addr = bpf_htonl(0x7f000001);

if (bpf_bind(ctx, (struct sockaddr *)&sa, sizeof(sa)) != 0)
return 0;

/* Rewire service 1.2.3.4:60000 to backend 127.0.0.1:60123. */
if (ctx->user_port == bpf_htons(60000)) {
orig = bpf_sk_storage_get(&service_mapping, ctx->sk, 0,
BPF_SK_STORAGE_GET_F_CREATE);
if (!orig)
return 0;

orig->addr = ctx->user_ip4;
orig->port = ctx->user_port;

ctx->user_ip4 = bpf_htonl(0x7f000001);
ctx->user_port = bpf_htons(60123);
}
return 1;
}

```

Relevant Helper function:
- [ ] bpf_bind

### Proposed solution

Enhance the netebpfext to implement callouts at ALE connect/bind redirect layers.

Calling bpf_bind() may not be possible from INETx_CONNECT attach type. For that, INETx_BIND attach time may be needed.

### Additional context

_No response_

Start with the referenced Linux selftest connect_force_port4.c and the proposed netebpfext ALE connect/bind redirect layers. Determine how BPF_PROG_TYPE_SOCK_ADDR programs attach to BPF_CGROUP_INETx_CONNECT and INETx_BIND, including the bpf_bind helper. Done means connect and bind redirect or rebind behavior is implemented and covered by tests for the relevant IPv4 and IPv6 paths.
