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:
#0 build/host/kb_8042/kb_8042.exe() [0x412421]

This provides us a way to inject interrupts during a test. If a test has
interrupt_generator() defined, it will run in a separate thread. The
generator can then trigger interrupts when it decides to. The current
running task is suspended while emulator is executing ISR.
Also fixes a bug that tasks run without scheduler notifying them during
emulator start-up.

To test drivers, we need a way to fake I2C periphrals. With this CL, a
fake peripheral can be done by declaring its own I2C read/write
functions. The fake I2C peripherals may return EC_ERROR_INVAL to
indicate it's not responding. The emulator I2C read/write call scans
through all registered I2C peripherals and uses the first response.
