Remove OTA partition from Espressif 4MB builds to make room for BLE, and then expand the firmware partition.

• non-UF2 boards: done by Expand Espressif non-usb firmware partitions #10424.
• ESP32-S2
• ESP32-S3: addressed by Make ESP32-S3 4MB boards use no-ota partition table #10458

This requires new bootloaders, I assume. We need to come up with a transition plan.
