ESP-IDF support and generic target platforms (#2303)

* Socket refactor and SSL * esp-idf temp * Fixes * Echo component and noise * Add noise API transport support * Updates * ESP-IDF * Complete * Fixes * Fixes * Versions update * New i2c APIs * Complete i2c refactor * SPI migration * Revert ESP Preferences migration, too complex for now * OTA support * Remove echo again * Remove ssl again * GPIOFlags updates * Rename esphal and ICACHE_RAM_ATTR * Make ESP32 arduino compilable again * Fix GPIO flags * Complete pin registry refactor and fixes * Fixes to make test1 compile * Remove sdkconfig file * Ignore sdkconfig file * Fixes in reviewing * Make test2 compile * Make test4 compile * Make test5 compile * Run clang-format * Fix lint errors * Use esp-idf APIs instead of btStart * Another round of fixes * Start implementing ESP8266 * Make test3 compile * Guard esp8266 code * Lint * Reformat * Fixes * Fixes v2 * more fixes * ESP-IDF tidy target * Convert ARDUINO_ARCH_ESPxx * Update WiFiSignalSensor * Update time ifdefs * OTA needs millis from hal * RestartSwitch needs delay from hal * ESP-IDF Uart * Fix OTA blank password * Allow setting sdkconfig * Fix idf partitions and allow setting sdkconfig from yaml * Re-add read/write compat APIs and fix esp8266 uart * Fix esp8266 store log strings in flash * Fix ESP32 arduino preferences not initialized * Update ifdefs * Change how sdkconfig change is detected * Add checks to ci-custom and fix them * Run clang-format * Add esp-idf clang-tidy target and fix errors * Fixes from clang-tidy idf round 2 * Fixes from compiling tests with esp-idf * Run clang-format * Switch test5.yaml to esp-idf * Implement ESP8266 Preferences * Lint * Re-do PIO package version selection a bit * Fix arduinoespressif32 package version * Fix unit tests * Lint * Lint fixes * Fix readv/writev not defined * Fix graphing component * Re-add all old options from core/config.py Co-authored-by: Jesse Hills <3060199+jesserockz@users.noreply.github.com>
