Kmake/deps/v8/tools/clusterfuzz/trials

It is possible to add trials from the source code side by adding the below line to clusterfuzz_trials_config.json:

{
  "app_args": "FLAG_NAME",
  "app_name": "APP_NAME",
  "probability": PROBABILITY,
  "contradicts": ["FLAG1", "FLAG2", ...]
}

• app_args: the name of the flag we want to add.
• app_name: the name of the app we are adding the flag for, this must be d8 on V8.
• probability: the probability of this flag to be selected.
• contradicts (optional): the flags that contradict the flag referred to in app_args. This will stop flags that contradict each other from being added in the same trial.
