Move the dexpreopting logic into Soong. Make modules will be
dexpreopted by executing the Soong logic in the standalone
dexpreopt_gen binary, which will generate scripts that will
perform dexpreopting for each module. Export global configuration
as JSON to $OUT/dexpreopt.config, which will be used by
dexpreopt_gen and Soong, and per-module JSON configuration that
will be used by dexpreopt_gen.

Bug: 120273280
Test: no differences to dexpreopt outputs on aosp_sailfish system/,
only expected changes to dexpreopt outputs on system_other
(.vdex files for privileged Soong modules no longer incorrectly
contain .dex contents).

In preparation for setting up another Kati stage, move some common
settings and tools into a common folder. This way it's a bit easier to
see that they're safe to use, and that they shouldn't depend on anything
outside of the common folder.
