Fix whitespace rendering in diff (#13415)

- Introduce new .code-inner class that sets the CSS attributes on
rendered code lines like view,blame and diff.
- Rename .wrap class to .word-break to reflect what it actually does
- Remove .raw which was only used on webhook page
- Set white-space: pre-wrap except on blame where it can break the
layout
