Move function declaration to shared header file to fix multiple -Wmissing-prototypes
warnings like below:

fs/btrfs/zstd.c:369:5: warning: no previous prototype for ‘zstd_compress_pages’ [-Wmissing-prototypes]
  369 | int zstd_compress_pages(struct list_head *ws, struct address_space *mapping,
      |     ^~~~~~~~~~~~~~~~~~~
