cmake: Update cmake-format to allow files to use up to 100 columns

[PatTheMav]

Description

Update cmake-format configuration to increase hard column limit to 100 characters.

Motivation and Context

To improve readability on modern displays and systems, it is considered good practice to encourage an 80-column limit but set the actual hard limit to 100 columns.

The changes in this PR serve as a good example for the improvements in legibility and readability this gives.
