Add HF 1x1 Trigger Primitives

This pull request adds HF 1x1 Trigger Primitives (TPs) while still providing the RCT-style TPs for backwards compatibility. Additionally HcalPacker was fixed to properly pack the trigger digis into the RAW.

This will require a new global tag: HcalLutMetadata_v3.00_mc (on CMS_COND_31X_HCAL)
Automatically ported from CMSSW_7_3_X #6257
