all: Remove tinytest component.

With the recent qemu (d9a0fdda9a7b0db55c1115b55bb1b83cd5ce739c and
0426934969d06aa649ba903f5408cb331b5b9c2d) and zephyr
(05cad7b56f5d460db26a468a05bfdeabe4a656db) changes to how their tests are
run, two things became unused:

- The tinytest framework, which embedded a set of tests and their expected
  output within firmware, so these tests could be run stand-alone.

- The `--write-exp` and `--list-tests` options to `tests/run-tests.py`,
  which were needed primarily to generated the expected test output for
  tinytest (also the associated `tests/run-tests-exp.py/.sh` scripts are
  now unused).

This commit removes the tinytest component and all its helper code.  This
eliminates a maintenance burden.
