testsuite: Use printk for all test output where possible.

- Remove the printf support leaving the direct printk support configured
  with TESTS_USE_PRINTK and all other output goes via a buffered vsniprintf
  call to printk.
- Control the test's single init for functions and global data with
  TEST_INIT and not CONFIGURE_INIT. They are now separate.

Updates #3170.
