Allow Kernel to link in both legacy libkern/zlib and new sys/contrib/zlib,

Description

Allow Kernel to link in both legacy libkern/zlib and new sys/contrib/zlib,
with an eventual goal to convert all legacl zlib callers to the new zlib
version:

  • Move generic zlib shims that are not specific to zlib 1.0.4 to sys/dev/zlib.
  • Connect new zlib (1.2.11) to the zlib kernel module, currently built with Z_SOLO.
  • Prefix the legacy zlib (1.0.4) with 'zlib104_' namespace.
  • Convert sys/opencrypto/cryptodeflate.c to use new zlib.
  • Remove bundled zlib 1.2.3 from ZFS and adapt it to new zlib and make it depend on the zlib module.
  • Fix Z_SOLO build of new zlib.
