Since the interrupt generator is now spawned right after the hooks task
and the generator can generate interrupts whenever it wants, it's
possible for an interrupt to fire before task switching is enabled.
When this happens, the main thread needs to be suspended so that the IRQ
can be serviced.

This commit changes the way in which tasks are started. Instead of
having all tasks marked as ready to run upon initialization, only the
hooks task is marked as ready to run. HOOK_INITs are now run at the
beginning of the hooks task. After the HOOK_INITs, the hooks task calls
back to enable the rest of the tasks, reschedules, and proceeds as
usual. This also allows the removal of checks for task_start_called().

Our code base contains a lot of debug messages in this pattern:
CPRINTF("[%T xxx]\n") or ccprintf("[%T xxx]\n")
The strings are taking up spaces in the EC binaries, so let's refactor
this by adding cprints() and ccprints().
cprints() is just like cprintf(), except that it adds the brackets
and the timestamp. ccprints() is equivalent to cprints(CC_CONSOLE, ...)
This saves us hundreds of bytes in EC binaries.

The implementation of trace dump has little to do with task scheduling,
so we should move it to a separate module for cleaner code. This
requires exposing some emulator-specific task info, as defined in
host_task.h.

Emulator test failures are sometimes hard to debug, especially when the
test is stuck somewhere and times out. Let's have the emulator dump
stack trace when an assertion fails or a test times out.
The produced stack trace is in this format:
