Fixes various deadlocks in ProjectRecovery which can occur during
shutdown. These include holding a lock in the worker thread, then
calling into the GUI thread which is attempting to lock the mutex.

Waiting for the thread to join in the GUI thread, whilst the worker
thread is waiting for the GUI thread to save

The ISISRAW pointer in LoadRawHelper is only required when a file
is being read and not when the object is constructed. Delaying the
creation of this instance cuts out a lot of work/logging when just
creating a LoadRaw instance that is not used.
Refs #22733

Hold a shared pointer to a workspace from the ADS rather than its name.
This way if it is deleted between the start of the saving step and end,
we can still carry on.

Algorithms are children and unmanaged to minimise their output footprint.
