Currently, we use an `UnrefQueue` which supposedly aims to transfer destruction costs to another thread. The implications of this unusual pattern can not be well understood because some allocators might free resources more efficiently if they are freed by the same thread that allocated them. In addition, `UnrefQueue` complicates the validation of thread safety in our engine. Lastly, our current usage of `UnrefQueue` triggers `ref()`, `unref()` atomic operations as objects are passed into the queue. These operations could be more expensive than the actual destruction.
With this PR we thus remove `UnrefQueue`. We can expect these changes to have a minor impact at most because we free most resources elsewhere in `ResourceSystem::updateCache`.
It can fail due to float arithmetic precision with error:
Expected equality of these values:
getAsString(lua, "moveAndScale")
Which is: "TransformM{ move(6, 22, 18) scale(0.5, 1, 0.5) rotation(angle=8.53284e-17, axis=(1, 0, 0)) }"
"TransformM{ move(6, 22, 18) scale(0.5, 1, 0.5) }"

We currently build a large map of a BSAFile's contents unused by Open MW. We already map archive contents in VFS. With this PR we remove the map from BSAFile and reimplement its only current use in BSATool.
