… options (hyperium#2472)

Add two new configuration methods to the Server builder:
  - `tcp_keepalive_interval()`: Sets TCP_KEEPINTVL socket option
  - `tcp_keepalive_retries()`: Sets TCP_KEEPCNT socket option

These options were already implemented in TcpIncoming but not exposed
through the Server builder API. This change allows users to fine-tune
TCP keepalive behavior for scenarios like:
  - Cloud load balancer idle timeout matching
  - NAT traversal requirements
  - Faster dead connection detection

The new options default to None (system default) and only take effect
when tcp_keepalive() is also configured.

  ## Motivation

`TcpIncoming` already supports `with_keepalive_interval()` and
`with_keepalive_retries()`, but these are not exposed through the
`Server` builder. Users need fine-grained control over TCP keepalive for
cloud LB timeout matching and faster dead connection detection.

  ## Solution

Add `tcp_keepalive_interval()` and `tcp_keepalive_retries()` methods to
`Server` builder, passing them through to `TcpIncoming` in
`bind_incoming()`. Both default to `None` and only take effect when
`tcp_keepalive()` is also set. Tests updated accordingly.
