Use the class loader context when optimizing secondary dex files

Record the class loader context for secondary dex loads and pass it to
dexopt during compilation.

The class loader context is passed from libcore every time a
BaseDexClassLoader is created and its recorded in the package dex usage
file.

Note that the context may be:
- unknown: if the dex file was not use after the the upgrade and its
context was not yet updated
- unsupported: if any of the class loaders from the loading context is
unsupported (only PathClassLoader and DelegateLastClassLoader are
supported).
- variable: if it changes over time, form one run to another.

In all the above cases the old compilation behavior is preserved for
now.(i.e. the dex file with be compiled with SKIP_SHARED_LIBRARY_CHECK)
