Advait Jain 72499dfa3a Add a MicroPrintf function that is independant of the ErrorReporter.
Additionally,
  * remove the global error reporter from micro_test.h
  * change all the kernel tests to make use of MicroPrintf
  * add a GetMicroErrorReporter() function that returns a pointer to a
    singleton MicroErrorReporter object.
      - This enables the current change to not spread beyond the tests.
      - Even if we move large parts of the TFLM code to make use
        MicroPrintf (in favor of error_reporter), there is still going to
        be shared TfLite/TFLM code that will need an error_reporter.

Next steps, if we want to continue down this path
  * remove the error_reporter from the TFLM functions and class
    implementations and instead use either MicroPrintf or
    GetMicroErrorReporter()
  * Add new APIs that do not have error_reporter to the TFLM classes and
    functions.
  * Ask users to switch to the new error_reporter-free APIs and
    depreacte the APIs that do make use of the error_reporter.
  * Remove the error_reporter APIs completely.

Prior to this change, we would have to use the ErrorReporter interface
for all the logging.

This was problematic on a few fronts:
 * The name ErrorReporter was often misleading since sometimes we just
   want to log, even when there isn't an error.
 * For even the simplest logging, we need to have access to an
   ErrorReporter object which means that pointers to an ErrorReporter
   are part of most classes in TFLM.

With this change, we can simply call MicroPrintf(), and it can be a no-op
if binary size is important.

If we find this approach useful, we can consider incrementally reducing
the usage of ErrorReporter from TFLM.

Progress towards http://b/158205789

starting to address review comments.
