clang-format: re-format for clang-19

clang-format-19 isn't compatible with the clang-format-18 output, so we
need to reformat the code with the latest version. A few parameters
in clang-tidy have been deprecated, so adjust the style file
accordingly.

See Ie2f6eb3b043f2d655c9df806815afd7971fd0947 for updated style.
See I88192b41ab7a95599a90915013579608af7bc56f for clang-19 enablement.

ncsid: skip setting mac address if it matches

There are cases where NIC keeps trying to set MAC
address of already set interface, which can lead
to ncsid turning interface down/up non-stop. A
workaround is to check if mac matches before setting.

ncsid: fix default wait time

The default wait time needs to shift with current timestamp, otherwise

Tested: bring down the interface to simulate the nic not ready, start
this script and verified that it loops every 10s. Then bring up the
interface, and see the route is setup with no issue

Our labs and production environment normally use this as the gateway

Tested: On a noisy lab network and verified that the script correctly
locks onto fe80::1 and switches away from other gateways it receives.

ncsid: update_ra_gw: Improve gateway discovery speed

The rdisc6 binary when run in a subshell buffers all of the output
instead of sending each line. This results in a long delay to figure out
the gateway address.

We can fix this by running it through `script`, which removes the
buffering and allows us to nearly instantly update our route.

Tested: Ran on our AMD Rome system and verified that the gateway was
quickly being updated.
