Remove unnecessary types: ITypeExport, TypeExport

remove subscription to IWorkspaceCacheService from non host workspace.

IWorkspaceCacheService is non-factory MEF workspace service which means it leaves forever. so anything subscribed to it will live forever as well.

this made some temporary workspace to live longer than expected.

Remove the term "whitelist"

**Bug:** Fixes DevDiv Bug 1185799

**Customer Scenario**
No customer scenario, per se.

There are a number of places where we use the term "whitelist", and one of them (a code comment) was flagged by Policheck. Given that our code is open I've gone ahead and simply fixed them all.

**Fix**
Several internal types were updated with new names, as well as various fields, locals, and a comment.

**Testing**
After the fix, the code still passes all of our unit and integration tests.

We have a couple of places where we check that the set of analyzer
assemblies is internally consistent and complete--that is, for any given
assembly in that set, all of its dependencies are satisfied by other
assemblies in the set.

We expect certain dependencies to be satisfied by the host, and so want
to ignore them if they are not found in the the analyzer assembly set.
We referred to these host-provided dependencies as a white list, but
Policheck does not like that term. Instead, we now refer to these as the
"ignorable assembly list".
