[foozzie] Use json for flags and experiments This will allow sharing the configs between Python and JavaScript based fuzzers.

[foozzie] Compare baseline/default in every run Previously we ran baseline (e.g. ignition) and one random secondary comparison configuration (e.g. turbofan) from the list of experiments. But Clusterfuzz imposes limitations on the total amount of fuzz tests. Therefore this change enables more throughput by always running the default configuration (ignition_turbofan like V8 is shipped) additionally to the baseline and the secondary configuration. This, hence, doubles the number of comparisons we run, with less than 50% additional runtime, since the slow baseline configuration is only run once. The experiments table is updated accordingly. Explicit entries running ignition_turbofan are removed (as it always runs now), instead some of the other configurations are increased in their relative percentage. We also get a few new configurations that didn't run before (e.g. forcing the slow path on x86).

[foozzie] Overhaul comparisons This reduces the pointer-compression experiment by 3% as it is in production since a while. This also uses turbofan when comparing across architectures as tests run faster and likely find the same or more relevant bugs.
