add Adafruit metro S3 16MB Flash, 8MB PSRam (espressif#8478)

* add Adafruit metro S3 16MB Flash, 8MB PSRam

also reorder to have feather boards next to each others

* correct SS pin to 21, also add NEOPIXEL_PIN

* change metro s3 psram type to opi, default SD_CS (SS) to input pull up

* remove psram qspi option
