Various fixes for async keystore.
* Added missing Tag::HARDWARE_TYPE and Tag::TRUSTED_CONFIRMATION_REQUIRED
* Made AuthorizationSet::hidl_data() safer to use.
hidl_data() initializes a hidl_vec with the internal data of
std::vector using setToExternal and returns it by value. This means
the returned temporay does not own the buffer which has the life cycle
of the AuthorizationSet. This is fine if passed as parameter to a
function where it is bound to a cont reference. But if the temporary
gets assigned to something with longer life cycle move semantics kicks
in and the buffer is now tracked by something with a longer life
cycle. This patch marks the returned temporary const, so that it can
no longer be moved. It can still be bound to a const reference, but
when assigned to a variable it must get copied.
* Add Filter function to AuthorizationSet.
