ESP32: Take away "tbeam" boards PSRAM to reclaim iram (#10036)

You read that right! Disable PSRAM on the ttgo-tbeam board to reclaim *iram*.

ttgo-tbeam.json is a copy of https://github.com/platformio/platform-espressif32/blob/v6.13.0/boards/ttgo-t-beam.json with HAS_PSRAM removed.

PSRAM support on OG-ESP32 involves a lot of iram usage thanks to iram-heavy workarounds that have been added to address hardware bugs.

See https://docs.espressif.com/projects/esp-idf/en/v4.4/esp32/api-guides/performance/ram-usage.html#optimizing-iram-usage
