Use RunWidget in Inelastic Data Reduction

Description of work

This PR removes duplicate code from the Data Reduction interface and ensures it uses the new RunWidget. It also removes the setup(), validate() and run() functions from all remaining tab classes because we no longer require to use them. We also do not require runTab and validateTab.

Having the RunWidget will allow us to work on two new features detailed by #37418 and #37201 . It allows us to easily roll out these new features to all tabs in the Indirect and Inelastic interfaces.

Fixes #37381

To do

[x] Remove instances of runTab()
[x] Remove instances of setup(), validate() and run()
[x] Wait for Tools RunWidget PR to be merged then rebase

To test:

Follow the testing instructions on this page https://developer.mantidproject.org/Testing/Indirect/DataReductionTests.html

This does not require release notes because it is a maintenance change
