* partition api changed from spi_flash* API to esp_partition* API and is abstracted as a C++ interface. * The old nvs encryption is still possible * changed default unit test app partition table * Partitions coming from esp_partition API are checked for generic flash encryption. If yes, an error is returned since generic flash encryption isn't compatible with nvs encryption * esp32, esp32s2 tests don't require nvs_flash but mbedtls now Closes IDF-1340 Closes IDF-858
