clang-format: Increase column limit from 80 to 120

[RytoEX]

Description

Increase the column limit in clang-format from 80 to 120.

Motivation and Context

Want to have longer lines. Others have asked us to use longer lines.

How Has This Been Tested?

I haven't done any build testing with this. This is a formatting change, so hopefully all CI builds will pass.

Types of changes

• Code cleanup (non-breaking change which makes code smaller or more readable)

Checklist:

• [x] My code has been run through clang-format.
• [x] I have read the contributing document.
• [x] My code is not on the master branch.
• [ ] The code has been tested.
• [x] All commit messages are properly formatted and commits squashed where appropriate.
• [x] I have included updates to all appropriate documentation.

@RytoEX We probably should try to make this happen soon-ish before the rush of merges for the next version of OBS takes place.
