[nat64] implement nat64 translator (ot::Nat64::Translator) (#7836)

Browse Source 
This commit:

- implements the core logic for translating packets for NAT64,
  including the public APIs exposed to platform daemons.

- includes changes for POSIX platform, use `OT_POSIX_NAT64_CIDR`,
  `OPENTHREAD_POSIX_CONFIG_NAT64_CIDR` for setting the CIDR for NAT64
  during build time.

- exposes `otNat64Send(otInstance *aInstance, otMessage *aMessage)`
  and `void otNat64SetReceiveIp4Callback(otInstance *aInstance,
  otNat64ReceiveIp4Callback aCallback, void *aContext)`.

| BORDER_ROUTER | OT_BORDER_ROUTER | Enables support for Border Router. This switch is usually combined with the BORDER_AGENT and UDP_FORWARD (or PLATFORM_UDP in case of RCP design) switches to build Border Router device. |
| BORDER_ROUTING | OT_BORDER_ROUTING | Enables bi-directional border routing between Thread and Infrastructure networks for Border Router. |
| BORDER_ROUTING_NAT64 | OT_BORDER_ROUTING_NAT64 | Enables NAT64 border routing support for Border Router. |
| NAT64_TRANSLATOR | OT_NAT64_TRANSLATOR | Enables NAT64 translator for Border Router. |
| BUILTIN_MBEDTLS_MANAGEMENT | OT_BUILTIN_MBEDTLS_MANAGEMENT | Enables the built-in mbedTLS management. Enable this switch if the external mbedTLS is used, but mbedTLS memory allocation and debug config should be managed internally by OpenThread. |
| CHANNEL_MANAGER | OT_CHANNEL_MANAGER | Enables support for channel manager. Enable this switch on devices that are supposed to request a Thread network channel change. This switch should be used only with an FTD build. |
| CHANNEL_MONITOR | OT_CHANNEL_MONITOR | Enables support for channel monitor. Enable this switch on devices that are supposed to determine the cleaner channels. |
