atomics: Disentangle 32bit and 64bit atomics configuration.

Allow for --enable-nonportable-atomics=upto32bit to disable 64bit atomic
builtins while still allowing for 32bit ones. yes/no still enables/disables
both (if available in the first place..).

By default (no --enable-nonportable-atomics setting), generic 64bit atomics are
forced for 32bit CPUs/systems, until we figure out how to properly align
apr_uint64_t (at least i[56]86 CPUs which could work with 64bit builtins
actually don't if the data is not 64bit aligned, assuming the same for other
32bit CPUs is safer).
