This changes current TASK() syntax to TASK_BASE() and TASK_NORMAL(),
where TASK_BASE is necessary for the EC to boot on a board and
TASK_NORMAL represents the task that can be removed in a test binary.
Tasks introduced by a test should be listed as TASK_TEST().
Note that this CL breaks current tests (many of them are broken anyway),
which will be fixed in up coming CLs.
