[CIFuzz] Support ALLOWED_BROKEN_TARGETS_PERCENTAGE (#3726) 
Currently we use Github action's inputs as inputs to cifuzz.
This means we need to do an extra step to convert each input into
an env var so our scripts can actually use it.
This is pretty bug prone and unnecessary, we should probably
get rid of this abstraction and switch to encouraging devs to set
the env vars directly.

OSS-Fuzz: Continuous Fuzzing for Open Source Software

Fuzz testing is a well-known technique for uncovering programming errors in software. Many of these detectable errors, like buffer overflow, can have serious security implications. Google has found thousands of security vulnerabilities and stability bugs by deploying guided in-process fuzzing of Chrome components, and we now want to share that service with the open source community.

In cooperation with the Core Infrastructure Initiative, OSS-Fuzz aims to make common open source software more secure and stable by combining modern fuzzing techniques with scalable, distributed execution.

We support the libFuzzer and AFL fuzzing engines in combination with Sanitizers, as well as ClusterFuzz, a distributed fuzzer execution environment and reporting tool.

Currently, OSS-Fuzz supports C/C++, Rust, and Go code. Other languages supported by LLVM may work too. OSS-Fuzz supports fuzzing x86_64 and i386 builds.
