Title: HPCC-7996 Introduce memory manager spill threshold option

Add a thor option to allow the memory manager to be configured, so that it can s
pill when it hits a certain threshold(%), default 80%.
The reasoning being, that if the memory manager waits until it is out of memory
before requesting memory to be freed, those requests can take some time (e.g. so
rt+flush to disk), and cause all other small memory consumers to block in the me
antime.
