Adjust vheap sizes for message handling processes in OTP 27 (backport #12208) #12508

  1. Adjust vheap sizes for message handling processes in OTP 27 

    OTP 27 reset all assumptions on how the vm reacts to processes that
buffer and process a lot of large binaries.

Substantially increasing the vheap sizes for such process restores
most of the same performance by allowing processes to hold more binary
data before major garbage collections are triggered.

This introduces a new module to capture process flag configurations.

The new vheap sizes are only applied when running on OTP 27 or
above.
