Tools: Testbench: Add system agent initialization

This patch fixes a segfault with null sof->sa pointer in
pipeline_schedule_copy() function. The bug has not been observed
with test topologies for processing pipelines but with other
topologies with fuzzer varied parameters.

The sa_init() is added to tb_pipeline_setup(). The scheduler_init_edf()
is a dependency. The two dummy functions platform_timer_get() and
clock_ms_to_ticks() are also added as dependency. The CMakelist for
library is edited to include agent.c build for testbench.

Fixes #3247
