69e121260e [tilelink2] Add unit tests for many TL2 components 
These tests mostly use the Fuzzer and RAMModel to check that adapters
correctly handle randomly generated legal traffic.

a421469754 tilelink2: change adapters to use TLAdapter(params, defaults)(node) 
This API makes it much more readable when you have multiple adapters
combined into a single line. The arguments for each adapter stay
beside the adapter.

For example, this:
  peripheryBus.node := TLWidthWidget(TLBuffer(TLAtomicAutomata()(TLHintHandler(legacy.node))), legacy.tlDataBytes)
becomes this:
  peripheryBus.node := TLWidthWidget(legacy.tlDataBytes)(TLBuffer()(TLAtomicAutomata()(TLHintHandler()(legacy.node))))
