JTAG: Use new withClock way of overriding clocks (#1072) 
* JTAG: Use new withClock way of overriding clocks

the override clock way is deprecated

* JTAG: use withClock instead of override clock

* JTAG:  extend Module for ClockedCounter

* JTAG: Don't use deprecated clock constructs

* JTAG: Remove another override_clock

* Rename "NegativeEdgeLatch"

because it's not a latch, it's just a register on the negative edge of the clock.

* Use the appropriately named NegEdgeReg

* JTAG: Rename another NegativeEdgeLatch

  consumed by emulator.cc for correct argument parsing and help text
  generation
- emits snippets in $(CONFIG).plusArgs via BaseCoreplex-set
  ElaborationArtefacts
- modify emulator/Makefrag-verilator to include $(CONFIG).plusArgs
- cleanup help text (docstring) for existing PlusArgs
