dropAllLocks causes Thread::yield several times which means more system
calls which means more thread switches which means slower

### What does this PR do?
Releasing heap access causes all the heap helper threads to wake up and
lock and then unlock futexes, but it's important to do that to ensure
finalizers run quickly.
That means releasing heap access is a balance between:
1. CPU usage
2. Memory usage
Not releasing heap access causes benchmarks like
https://github.com/oven-sh/bun/pull/14885 to regress due to finalizers
not being called quickly enough.
Releasing heap access too often causes high idle CPU usage.
For the following code:
```
setTimeout(() => {}, 10 * 1000)
```
command time -v when with defaultRemainingRunsUntilSkipReleaseAccess =
0:
>
> Involuntary context switches: 605

command time -v when with defaultRemainingRunsUntilSkipReleaseAccess =
5:
>
> Involuntary context switches: 350
>
command time -v when with defaultRemainingRunsUntilSkipReleaseAccess =
10:
>
> Involuntary context switches: 241

Also comapre the #14885 benchmark with different values.
The idea here is if you entered JS "recently", running any
finalizers that might've been waiting to be run is a good idea.
But if you haven't, like if the process is just waiting on I/O
then don't bother.
