Update cross compiler gcc version

[nycrat]

Description

As a part of c++ 20/23 support in our robot software, we updated the cross compiler to use gcc 14.3.0. This has been done, but the gcc path has not been updated from 8.5.0 yet. Also, the cross compiler version is just implicitly whatever is on main on this repo: https://github.com/UBC-Thunderbots/Software-External-Dependencies which initially caused this bug. So, this PR also pins the cross compiler version to a specific commit so this doesn't fail in the future.

Testing Done

Length Justification and Key Files to Review

Review Checklist

It is the reviewers responsibility to also make sure every item here has been covered

• Function & Class comments: All function definitions (usually in the .h file) should have a javadoc style comment at the start of them. For examples, see the functions defined in thunderbots/software/geom. Similarly, all classes should have an associated Javadoc comment explaining the purpose of the class.
• Remove all commented out code
• Remove extra print statements: for example, those just used for testing
• Resolve all TODO's: All TODO (or similar) statements should either be completed or associated with a github issue

gcc 14.3.0 gives error without make_optional because it would call the default move constructor for Predict which has eigen matrices that are technically uninitialized.
