[master] RFR: OMWorld: Decouple deflation and table sizing [v3]

[Axel Boldt-Christmas]

> The change reverts all changes to deflation and moves the resizing of the OMWorld ConcurrentHashTable to the service thread. Using a similar logic to how we resize the Symbol- and StringTables. 
> 
> The option to shrink the table is taken out and can be reintroduced at a later date as an enhancement. To do it correctly the interactions with deflation needs to be figured out.
