boot: Provide a Kconfig to enable faking the boot

Browse Source 
This feature was designed for tracing but can be useful for debugging
too, since it is possible to examine the state of the system just before
handing off to the OS.

Provide a separate CONFIG_BOOTM_FAKE_GO option to allow this feature to
be used separate from tracing. Enable it for the EFI app.

Provides a way to fake the boot, so that almost everything is done
to prepare for the boot, but the jump to the OS does not actually
happen. This can be useful for debugging.
