kunit: tool: refactoring printing logic into kunit_printer.py
Context:
* kunit_kernel.py is importing kunit_parser.py just to use the
print_with_timestamp() function
* the parser is directly printing to stdout, which will become an issue
if we ever try to run multiple kernels in parallel
This patch introduces a kunit_printer.py file and migrates callers of
kunit_parser.print_with_timestamp() to call
kunit_printer.stdout.print_with_timestamp() instead.
Future changes:
If we want to support showing results for parallel runs, we could then
create new Printer's that don't directly write to stdout and refactor
the code to pass around these Printer objects.
