fuzz: add a new fuzzer testing memory allocation failures (#1818)
Try to fuzz error paths triggered by allocation errors.
Fix some errors already found by this new fuzzer.
Basic idea taken from: https://github.com/harfbuzz/harfbuzz/pull/2566/files
`FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION` is a standard define used to
(not)compile specific code in fuzzing builds.
See: https://llvm.org/docs/LibFuzzer.html
