This operation is formally defined as rounding down a potential stack pointer value to meet CPU and ABI requirments. This was previously defined ad-hoc as STACK_ROUND_DOWN(). A new architecture constant ARCH_STACK_PTR_ALIGN is added. Z_STACK_PTR_ALIGN() is defined in terms of it. This used to be inconsistently specified as STACK_ALIGN or STACK_PTR_ALIGN; in the latter case, STACK_ALIGN meant something else, typically a required alignment for the base of a stack buffer. STACK_ROUND_UP() only used in practice by Risc-V, delete elsewhere. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
