31b113b649 fix(esp_tee): Fix TEE attestation stack protection fault with secure boot enabled 
- Increased the TEE stack when secure boot is enabled
- Also, generate a build error when the generated TEE binary image size is
  greater than the TEE partition size

0964024484 refactor(esp_tee): Adopt Picolibc as the default LibC for ESP-TEE build 
- Also fixed an issue where NewLib ROM APIs, when called from TEE, were
  using the syscall table located in the REE SRAM. This could be abused
  as an attack vector to invoke illegal functions from the TEE.
  To prevent this, the syscall table is now switched to the TEE-specific
  copy during every M-U mode transition.
