J. Nick Koston d143df3c49 [wifi/rp2040] Add stable wifi-capability helpers for device-builder
Add public helpers so the device-builder dashboard backend
(esphome/device-builder) doesn't have to import the internal
NO_WIFI_VARIANTS list / BOARDS dict to decide whether its basic-
setup wizard should emit a wifi: block:

- esphome.components.wifi.has_native_wifi(*, platform, board=None,
  variant=None) - central dispatcher that takes whichever
  platform-relevant fields the caller has and routes to the right
  per-platform check internally. As ESPHome adds new platforms
  (5-6 planned), this is the single place to teach them about
  Wi-Fi capability - external tooling does not have to grow a
  parallel per-platform switch.
- esphome.components.wifi.variant_has_wifi(variant) - building
  block for the ESP32 branch (False for H2 / P4 which require
  esp32_hosted).
- esphome.components.rp2040.board_id_has_wifi(board_id) - building
  block for the RP2040 branch (existing no-arg board_has_wifi()
  unchanged, now delegates to the new helper). New name (rather
  than overloading board_has_wifi) so device-builder can feature-
  detect ESPHome support via try/except ImportError on the new
  symbol - an older ESPHome would import board_has_wifi
  successfully but raise TypeError on the explicit-arg call,
  defeating the fallback.

All three wrap implementation-detail tables (NO_WIFI_VARIANTS,
the generated BOARDS dict) with explicit-arg signatures + tests,
so device-builder pins against a stable surface and a future
refactor of the underlying tables doesn't silently break the
wizard.

Same shape as the device-builder API stabilisation in #16206
and #16290.

Tests for ESPHome

This directory contains some tests for ESPHome. At the moment, all the tests only work by simply executing esphome over some YAML files that are made to test whether the yaml gets converted to the proper C++ code.

Of course this is all just very high-level and things like unit tests would be much better. So if you have time and know how to set up a unit testing framework for python, please do give it a try.

When adding entries in test_.yaml files we usually need only one file updated, unless conflicting code is generated for different configurations, e.g. wifi and ethernet cannot be tested on the same device.

Current test_.yaml file contents.

Test name Platform Network BLE
test1.yaml ESP32 wifi None
test2.yaml ESP32 ethernet esp32_ble_tracker
test3.yaml ESP8266 wifi N/A
test4.yaml ESP32 ethernet None
test5.yaml ESP32 wifi ble_server
test6.yaml RP2040 wifi N/A
test7.yaml ESP32-C3 wifi N/A
test8.yaml ESP32-S3 wifi None
test10.yaml ESP32 wifi None
