all: Remove the zlib module.
This will be replaced with a new deflate module providing the same functionality, with an optional frozen Python wrapper providing a replacement zlib module. binascii.crc32 is temporarily disabled. This work was funded through GitHub Sponsors. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>pull/11905/head
