[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.

About the project

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
