6cb368fbbe [libos] Retain red zone area and FLAGS unmodified across syscall 
1. The previous implementation of __occlum_syret usse the red zone to
save the register temporarily, which may overwrite the red zone area.
This change avoids using the red zone when handling syscall.

2. Save and restore the FLAGS register before and after the operations
on PKRU to keep the FLAGS unmodified.

12cb488f36 [libos] Fix vulnerable nonce in DCAP verifier 
This commit fixed a security issue in the dcap verifier. The issue was caused by the '[in, out]' attributes of pointer parameter qve_report_info in the ocall function occlum_ocall_verify_dcap_quote(). This led to the vulnerability where the protected qve_report_info.nonce field in libos could be arbitrarily rewritten by attacker outside libos.
