Reland: Get the dex2oat host tool path from module dependency on the
binary module.
This uses the Once cache for GlobalSoongConfig to propagate the dex2oat
path from a module dependency to the singletons (both the one that
writes out dexpreopt_soong.config and the one that creates the
dexpreopted boot images). Unless dexpreopting is disabled altogether
through DisablePreopt in dexpreopt.config, that means:
- We must ensure at least one module registers a dex2oat tool
dependency and resolves a GlobalSoongConfig using it, or else the
singletons fail. That means we litter dex2oat dependencies in java
modules even when they won't get dexpreopted and hence don't really
need them.
- We still assume there's at least one java_library or android_app in
the build.
This relands https://r.android.com/1205730 without changes - the
necessary fixes are in the child CLs.
