David Cermak 0eb18951be lwip: Add config for DHCP client id; Fix DNS server idx assert issue ...

This commit brings two esp-lwip fixes to IDF:

1) Add configuration to disable DHCP client identification
2195f7416f
This config could be used to disable option 61 in DHCP packets, so that
clients will be identified by their  chaddr only.
(This is the lwip upstream original behaviour)

2) Fix server_idx increasing to DNS_MAX_SERVERS and trigger the LWIP_ASSERT
5a567d52f7
When lwip doesn't have DNS server and resolve a domain address, the server_idx
will increase to DNS_MAX_SERVERS, which will trigger the LWIP_ASSERT and make device crash.

Closes https://github.com/espressif/esp-idf/issues/7912
