Re #22515

Update to clang-format-5 and reformat the codebase 

This commit removes the validation error for workspace groups which results in an error shown on the GUI. Instead validation is skipped for group workspace inputs to the efficiencies workspace property. The reason for this is that validateInputs is not called when the algorithm is run from a script. Therefore we get the same behaviour from the gui and the script, where the algorithm will be called on each member of the group initially. This could be improved further but is out of scope of this PR.

Re #23061

This fix adds a guard against workspace groups in the PolarizationCorrectionWildes algorithm's validateInputs. The algorithm dialog lets you select a workspace group if all of its members are valid matrix workspaces; however, a group is not valid input for this property.

Re #22997

This commit adds a temporary fix for an unhandled exception in validateInputs. The exception occurs when opening AlgorithmDialog on a group workspace. This first calls validateInputs on the group for the dialog, before calling it on the individual workspaces when executing the algorithm. Workspace groups are not currently handled. Adding full validation for groups is beyond this PR so this fix just skips validation rather than throwing the exception.
