Enforce hidden apis usage in product(soong)

Only if PRODUCT_ENFORCE_PRODUCT_PARTITION_INTERFACE is set,
every app and java library in product cannot use hidden APIs anymore.

checkSdkVersion() checks if sdk_version of app and library is narrow enough,
checkLinkType() checks every library that app links agianst

Bug: 132780927
Test: m
Test: set PRODUCT_ENFORCE_PRODUCT_PARTITION_INTERFACE, and check whether build
error occurs.
