Use clearer names to indicate a notification of a request, a function that performs the action, and a notification
of a result from that action.

Re #26536

This is no longer necessary now that the instrument is stored in and set
by the main window

Re #26536

Take this from the main window's instrument, rather than using the
program default instrument index, which will not be correct if creating
subsequent batches after changing the instrument.

Re #26536

- We no longer need to notify a settings update for Experiment and
Instrument tabs because they will be updated when the instrument list is
initialised
- We no longer need to check if mainPresenters are checked because this
will always be the case now initialisation is done after all tabs are
fully set up

Re #26536

Setting initial state is done by the main window after adding a new
batch is complete and all presenters know their parent presenter. Move
the initialisation of the instrument list to the same place.

Re #26536

Move the update from the original request notification to the one that
actually does the update. Also add some missing unit tests for all
different calls related to updating the instrument.

Re #26536

The instrument has been moved to the main window so that it can be
synchronised between batches

Re #26536

Also remove some unused code to do with the slit calculator, which is
not currently impemented and will not be implemented in the runs
presenter when it is added.

Reload instrument when chunking

Improved workspace grouping in ReflectometryISISLoadAndProcess

When skipping logs in chunking mode on SNAP, the instrument needs to be
reloaded in order to take the logs into account for calculating TOF->d
conversions.

There is no additional test because the file that exercised the bug is
16GB.
