Add target and pass_string parameters to the renode test script to fix #46186

This allows the `test_with_renode.sh` script to be called via the
makefile with all the parameters needed to run on a given target, while
also staying consistent with the other test scripts.

As a result of this change, the makefile is passing in the following
parameters to the test scripts:
 #1 - test binary path
 #2 - string to determine that test passes
 #3 - target

Parameter #3 is only used for `test_with_renode.sh`

Manually tested that the following commands now pass:
```
make -f tensorflow/lite/micro/tools/make/Makefile TARGET=bluepill test_kernel_add_test
make -f tensorflow/lite/micro/tools/make/Makefile TARGET=stm32f4 TAGS=cmsis-nn test_kernel_fully_connected_test
```
