Description of changes:
The upcoming CBMC version 6 release includes changes that may affect existing proofs. This PR will make sure that aws-c-common PRs are not negatively impacted by this release. After releasing CBMC version 6 we will issue a follow-up PR that will return aws-c-common to using CBMC's latest release, and will include any changes to proofs that may be necessary to support the new version.

**Issue:**
The proofs broke unexpectedly when CBMC 6.0.0 was released, since we were using "latest". We pinned the version back to  5.95.1 in a [recent PR](#1124) to get CI working again.

**Description of changes:**
- Upgrade to CBMC 6.0.0
    - For all tools used in proofs, stop using "latest". Pin the exact version, so we're not caught off-guard by unexpected upgrades again in the future
- Fix proof code to work with CBMC 6
