Feature switches

Every HF_CORE_ENABLE_* switch, its default, what turns it on, what it compiles and the definition it adds.

Set a switch before including cmake/hf_core_build_settings.cmake; a switch you leave unset takes the default. "Host build" is the value the top-level CMakeLists.txt uses for the host tests. "Turned on by" lists the switches that set it automatically.

Read from cmake/hf_core_build_settings.cmake and CMakeLists.txt.

Optional interfaces add their Esp* (or Stm*) source and ESP-IDF component: UART adds EspUart and esp_driver_uart, CAN adds EspCan and esp_driver_twai (ESP-IDF 5.5 and later), USB_SERIAL_JTAG adds EspUsbSerialJtag, PWM adds EspPwm, PIO adds EspPio. HF_CORE_ENABLE_CANOPENNODE needs HF_CORE_ENABLE_UTILS_CANOPEN, an upstream CANopenNode checkout at HF_CORE_CANOPENNODE_ROOT and the application's object dictionary at HF_CORE_CANOPENNODE_OD_DIR (see CANopen).
