[tb] Add support to trace retired TCDM operations #71

Summarize the changes concisely

Changelog

Added

Added the ability to Trace the operations retired by the TCDM adapters. When XQueue = 1, Queue operations, AMO and Load/Store operations are traced; when Xqueue = 0, only Load/Store operations are traced. This tracing capability is not supported on Verilator since a hierarchical reference to signals is not allowed in Verilator.

Parametrization fixes to systolic queues software implementation

…tomic extension, illegal)

- add interleaving and fix data dependency - hotfix to enforce data dependency in dummy pop/push

- generalize systolic_init() - add additional grid mappings

- change PEs role names - add different core mapping - flush queues at the end of execution

- fix illegal multi queue pop - increase performance via fixed cyclical pattern - add shuffling of MACs to hide accelerator latency
