Don't expand CRLFs when normalizing text during merge
Disable CRLF expansion when convert_to_working_tree() is called from normalize_buffer(). This improves performance when merging branches with conflicting line endings when core.eol=crlf or core.autocrlf=true by making the normalization act as if core.eol=lf.
