feat(precompiles)!: SHA-512 implementation [DRAFT]

[Sofianel5]

This PR introduces SHA512_EXTEND and SHA512_COMPRESS syscalls for SHA-512 extend and compress functionality respectively. As of right now, the implementations are not correct as it still using 32bit values instead 64. The purpose of this draft PR is to check in with the succinct team regarding a bug in SHA256_EXTEND. The following tests are failing:
