Increase MAX_CACHED_PROCESSES config

In performance testing, this improves performance on devices with
high RAM as they're able to reduce cold starts.
This regresses performance on low RAM devices because we spend

due to LMK.
I'm seeing the same results consistently across a wide range of
form factors (phones, tablets, watches, TVs, automotive head
units).
