common:test: refactor test_util.h to accommodate Zephyr

This change refactors test functionality in test_util.h to better
accomomdate zTests. This is done by:
* Removing the shim version of test_util.h. This was causing a
  conflict that made it harder to tell what's being used. This
  involved migrating some needed code over:
  - Defining different TASK_PARAMS.
  - Defining test_pass for Zephyr tests.
* Creating a macro (DECLARE_EC_TEST) that will automatically
  handle creating the individual test functions for both
  platform and Zephyr tests.
* Creating a macro (TEST_MAIN) that will automatically handle
  creating the main test entry function. This use to be
  test_main(void) for Zephyr and run_test(int, char**) for
  platform/ec. To do this we'll be removing the int, char**
  arguments from platform/ec. This may result in some tests
  having to be refactored, but overall should improve the
  test codebase as tests should remain deterministic (i.e.
  not depend on any outside arguments/parameters).
* Creating some common ztest_ function/macros that will
  allow writing platform/ec tests in a zephyr like style.
  see test/base32.c for an example.
* Update the type of __shared_mem_buf to match Zephyr. This
  was causing an issue now with the full test_util.h in
  zephyr/test/system/.
