Propagate profile_guided requirement of imports to top-level apex
For prebuilts, the dexpreopt rules of system server jars are now
generated from the context of the top-level prebuilt apex and not in the
context of the shim java_import modules. Since
`dex_preopt.profile_guided` property is defined in java_import, this
needs to be bubbled up to the top-level apex. This will be done using
deapxerInfo. If profile_guided of a transitive java_import is true, the deapexed .prof file will be
set as dexreopter.inputProfilePathOnHost before invoking
dexpreopter.dexpreopt. This ensures that only that java_import undergoes
profile guided dexpreopt, and not every other transitive java_import
