This change add support for CFG_CORE_STACK_PROTECTOR{,_STRONG,_ALL}
and CFG_TA_STACK_PROTECTOR{,_STRONG,_ALL}. This flag enable the
compiler stack overflow protection feature -fstack-protector* and
also generate random stack canary value on kernel boot and TA entry.
Weak function plat_get_random_stack_canary() can be override by
platform to provide random stack canary value for the core kernel.
