Pass privileged dexpreopt module configuration to Soong

Pass DONT_UNCOMPRESS_PRIV_APPS_DEXS, PRODUCT_LOADED_BY_PRIVILEGED_MODULES,
DEX_PREOPT_DEFAULT, and WITH_DEXPREOPT to Soong so it can determine when
to store uncompressed dex files in APKs and when to strip them.

Also convert DEXPREOPT.$(TARGET_PRODUCT).$(LOCAL_MODULE).CONFIG=disabled
to a DEXPREOPT_DISABLED_MODULES list, and export it to Soong.

Test: m checkbuild
