SF: Introduce TransactionTrace testsuite

Hassle free way to test and validate whether a sequence of
transactions will produce the expected front end state(s). Test
runs through all testdata/transactions_trace_*.winscope files,
generates layer states and checks if the states match the
corresponding layer trace in testdata.

Test: transactiontrace_testsuite
