Update CMake tooling to use 128 byte key files (a 4-way share of the 32 byte key). Also temporarily update the enc_bootloader to deshare this key - the actual fix will need to be in aes.S.
Add data_max_size to prevent overwriting the bootloader with data from flash
Also shrink the space allocated for the bootloader to 32K (plus 8K scratch)
Also switch to random default key
This is not necessary anymore, now picotool writes the AES key to otp json files Fixes #613
CK_JITTER is removed as the enc_bootloader runs from XOSC not ROSC
This includes the changes from #553
This is useful for testing decryption with large files

This adds a self-decrypting binary to demonstrate raspberrypi/pico-sdk#2315 and raspberrypi/picotool#207 - it requires both of those and raspberrypi/pico-sdk#2182 so should only be merged once those have been merged
Also fixes #613 in passing, as that is now handled by picotool.
