Error response for unmapped address or forbidden read/write access (#168)

* feat: add ability to enable error output on the cpuif, when decoding errors occur (generate_cpuif_err in API).

* fix: move signal to new place (after automatic vers)

* feat: add info about new api (generate_cpuif_err)

* fix: repair readback with latency

* Adding generate_cpuif_err argument to peakrdl-regblock to generate cpuif error response, when the address is decoded incorrectly

* add sw rd or/and wr attribure error response related and add error respone for external mem

* add sw rd or/and wr error response test

* add sw rd or/and wr error response for external register test and fix generation of rtl logic for external register

* add sw rd or/and wr error response for external mem test

* add sw rd or/and wr error response for apb3 imterfaces driver

* add error response test for APB4, AXI4Lite and Avalon interfaces

* rename --generate_cpuif_err to --generate-cpuif-err

* style: minor typo fixes and test clean-up

* refactor: move expected error check inside write/read functions

* feat: add error response check to OBI testbench interface

* feat: split generate-cpuif-err option into err-if-bad-addr and err-if-bad-rw options

* feat: add err_if_bad_addr/rw to cfg_schema

* feat: extend cpuif_err_rsp test to cover all combinations of bad_addr/bad_rw

* style: lint fixes

* fix: removed redundant if node.external condition to help coverage

* Fix dangling hwif_in signals in testcase
