Add dexpreopt files to ALL_MODULES.$(m).INSTALLED

We're trying to make FULL_SYSTEMIMAGE_DEPS more accurate to remove the
need for `m installclean`. The dexpreopt files did not show up in
FULL_SYSTEMIMAGE_DEPS, because they were installed with a custom
post-install command.

The dexpreopt implementation is shared between soong/make, which means
a lot of it happens at execution time for make. However, we have enough
information to guess what files to install will be inside the zip file.

Add an execution-time check that our guess is correct, and then add
the guessed files to `ALL_MODULES.$(m).INSTALLED`.

This also allows us to remove the post-install command, and just
generate rules to install the files we want directly.

Bug: 205632228
Test: full build on an internal product that uses dex-preopted make modules
