Support building a "flashing application" that one may run from an
existing bootloader. This flashing application will then flash the
main CanBoot binary to the start of flash.

Some boards require an initial gpio state in order to start USB. Port
the initial_pins capability from Klipper to provide that support.
This also synchronizes scripts/buildcommands.py with the latest code
from Klipper.

Move command handlers from canboot_main.c to flashcmd.c. Move startup
code to sched.c. Rename remaining bootloader entry code to new
bootentry.c file.

There is no need for a custom check_blink_time() function as this can
be done from a new led_blink_task().

Move the low-level command parsing and encoding code from
canboot_main.c to a new command.c file.
Standardize the parameters and naming for command handlers. Rename
send_ack() to console_send_ack() and rework parameters to be similar
to command handlers.

Add the sched.c code and associated DECL_INIT(), DECL_TASK() macros so
that it is easier to import low-level Klipper code into the CanBoot
repo.
These additional code wrappers do not increase the overall binary size
as gcc does a good job of inlining the wrappers and removing unused
code during the compile process.
