Respect line endings from API calls

What does this MR do?

Set default autocrlf to false to keep user's line endings because gitlab should not modify user input on API calls. Reverts gitlab-foss!858 (merged) because it should use other APIs and/or another mechanism and keep source file line endings.

Fixes #21431 (closed) also needs gitaly!1744 (closed) and omnibus-gitlab!3852 (closed)
