- Move ibex_tracer_defines.sv and ibex_defines.sv out of the 'include'
directory, since these files are not actually included.
- Remove ibex_config.sv, it's mostly unused code. The remaining defines,
SYNTHESIS, ASIC_SYNTHESIS, TRACE_EXECUTION, and CHECK_MISALIGNED should
be set through command-line flags to the simulation/synthesis tools.

This commit switches the ibex core from a custom debug system to an
execution-based, standard RISC-V debug system. The port is based on a
port done for the RI5CY core.
This change has been informed by advice from the lowRISC legal
committee.
