Move application_check_valid() in bootentry.c to armcm_boot.c and make
the check specific to the ARM cortex-m. On these ARM machines it is
easier to validate the application stack address.
Also rename jump_to_application() to application_jump().
Also rename flash_read_block() to application_read_flash() and move to
armcm_boot.c .

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.
