[Feature #22236] Allows to give a time budget to YJIT. When YJIT goes over the budget it pauses compilation until the budget is raised. It is best effort, YJIT may go over, or have no choice but to compile in some cases, but the goal is to be able to limit the CPU time overhead of YJIT during warmup, so that it's spread over a longer period of time and doesn't impact service latency as much.
