Replace some custom rules with BUILD_PREBUILT.
Move tools from ALL_PREBUILTS to BUILD_PREBUILT. All of them are already
in PRODUCT_PACKAGES in build/target/product/base.mk.
Remove uses of ACP and replace with core build system macros or 'cp'

Add a new preload tool based on hprof dumps. This means that only
a userdebug build (to adjust the pre-existing preloaded-classes
file) is required now, not a recompiled runtime.
