[zlib] Wrap deflate crc_folding and fill_window_sse features in guards
Wrap these deflate features in their #ifdef BUILD.gn feature guards to
prevent BUILD.gn errors and ease code searching.
Move the Intel-specific <immintrin.h> include file for fill_window_sse
inside of it feature guard (to allow an #elif for fill_window_arm that
may arrive here in future, maybe).
