Fixed performance counter test, fix for issue #319

Created by: Silabs-ArjanB

Fix for https://github.com/openhwgroup/core-v-verif/issues/319 doing the following:

  • Removed outdated core-v-verif/cv32/tests/programs/custom/counters (this was an out-of-date subset of hpmcounter_basic_test)

  • Fixed hpmcounter_basic_test to be tolerant against wait states on both instruction and data interfaces

  • Added hpmcounter_hazard_test, which is not tolerant against wait states on the OBI instruction interfaces (it should only be run without wait states on the instruction interface; wait states on the data interface are allowed) @MikeOpenHWGroup can you finish this pull request by:

  • Making sure that hpmcounter_hazard_test is run without wait states on the OBI instruction interface

  • Updating the regression list for the removal of 'counters' and the addition of 'hpmcounter_hazard_test'
