Ensure that enum values are used When assigning `pull_up_en` and `pull_down_en`
fields of `gpio_config_t`. Helps avoid `invalid conversion` errors when
building those code snippets in C++.
Currently, several examples do not explicitly state their component
dependencies, relying instead on the default behavior that includes all
registered components and commonly required ones in the build.
Explicitly adding component dependencies can reduce build time when
set(COMPONENTS main) is used.

Fixes a potential null pointer dereference in `esp_netif` when PPP mode is enabled.
In the Ethernet event handler, `esp_netif_dhcps_start()` and `esp_netif_dhcps_stop()`
are now only called if `netif` is non-null (in provisioning mode when
the actual TCP/IP stack from IDF is used, in work mode the `netif` is
null, since the trafic is simply forwarded between wireless and wired
networks without TCP/IP stack involved)
