Drop the comp module

opensslfeatures.h has long defined OPENSSL_NO_COMP and the build with
ZLIB was broken in openssl(1) since 2015 and in libcrypto since 2022.
ZLIB was unifdefed a while ago, now we can retire the public API.

The comp.h header stays devoid of code because a number of ports use it
for historic reasons.
