CL 1.1.8: Rename fork merge to bellatrix

[g11tech]

Motivation
As per specs CL 1.1.8, fork merge is being renamed to bellatrix as merge will be more specifically used for the event of merge of EL into PoS.
FYI Empty place holder files are for bellatrix/transition and bellatrix/fork scenarios planned to be added as a separate PR, tracked here: #3541

This PR renames the relevant fields, files, types from fork merge to bellatrix

Closes #3575
