remove CIRCUITPY_LEGACY_4MB_FLASH_LAYOUT = 1 on ESP32, ESP32-C3, ESP32-C6 boards

dhalbert · dhalbert · commit 775fa2380517 · 2025-06-13T13:04:35.000-04:00
This combines ota_0 and ota_1 into ota_0, but leaves the user filesystem in the same place.
dualbank is already turned off on these boards.
Also restores some modules that were turned off for space reasons.
