tests/fuzzers: added bn marshaling fuzzers #32053 (#1228) 
Adds marshaling fuzzing for G1 and G2 to oss-fuzz.

Also aligns the behavior of the google library to that of gnark and
cloudflare, which only ever read the first 64 / 128 bytes of the input,
regardless of how long the input is

are too big". Also, readme.md says curve P384 should use AES192 not AES256.

d2ac7d0987 crypto: fix build when CGO_ENABLED=0 (#19121) 
Package crypto works with or without cgo, which is great. However, to make it
work without cgo required setting the build tag `nocgo`. It's common to disable
cgo by instead just setting the environment variable `CGO_ENABLED=0`. Setting
this environment variable does _not_ implicitly set the build tag `nocgo`. So
projects that try to build the crypto package with `CGO_ENABLED=0` will fail. I
have done this myself several times. Until today, I had just assumed that this
meant that this package requires cgo.

But a small build tag change will make this case work. Instead of using `nocgo`
and `!nocgo`, we can use `!cgo` and `cgo`, respectively. The `cgo` build tag is
automatically set if cgo is enabled, and unset if it is disabled.
