Andrew Boie 618426d6e7 kernel: add Z_STACK_PTR_ALIGN ARCH_STACK_PTR_ALIGN 
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.
