.git-blame-ignore-revs: Ignore Line Ending and Uncrustify only commits (

#219)

## Description

Adds commits that only applied Uncrustify formatting or converted
line endings to a .git-blame-ignore-revs file so they are ignored
by git blame. This is supported by GitHub:

      like filter-branch can automatically update relevant SHAs.
