[sw] Refactor exporting to only use BIN_DIR
We build code in the object directory (build-out, $OBJ_DIR), and then export it
into the bin directory (build-bin, $BIN_DIR). Within BIN_DIR, we
conventionally follow/mirror the directory structure in the source tree.
Before this patch we constructed the sub-directories $BIN_DIR/sw/host
and $BIN_DIR/sw/device in build_consts.sh, and passed them individually
to meson. After this patch, we only pass $BIN_DIR to meson, and let its
build logic figure out the rest.
This allows for a simplification in the meson logic without changing the
directory structure we produce.
The motivation for this change is the pending addition of the sw/otbn
directory, which would duplicate the same functionality for a third
time.
