Runs clang-tidy pass by ref across the codebase to fix-up various
warnings we are seeing in cppcheck

Hand-fixes some cppcheck warnings, this was work prior to fixing the
cppcheck target.

Also updated class_maker.py

This commit replaces all header guards in DataHandling with #pragma once

Reuse map from NeXus file getEntries prevents creation and destruction
of std::map
addressing clang-format

This commit changes the call of workspace->x(0) to workspace->points(0) because of this I no longer need to check if the workspace is a histogram or not.

re: #27774

This commit creates an algorithm `SaveRMCProfile` to output an ascii file with the format corresponding to a file used by the RMCProfile package. the output file contains only the x and y data from a workspace with a header containing the number of y values in the file on the first line, and on the second line the type of function contained within and a title for the data.

re: #27774

The format of the sample environment xml file has been extended to support
loading a .stl file for each environment component. An example spec file
has been created in ISIS/Pearl.xml. This can be used when running the
Algorithm SetSample
Various SampleEnvironmentXXX units have been moved out the Geometry package
into the DataHandling package to facilitate this because they needed to
access the STL loading code in DataHandling
SetSample contains some features for overriding the sample geometry if the
geometry is a CSGObject. This has been sidestepped for mesh geometries.
The methods setId and setMaterial have been moved up to IObject because
it's useful to have them applicable to all objects (CSG, mesh)
Some of the repeated code in SetSample, LoadSampleEnvironment (and now
SampleEnvironmentSpecParser) has been centralised in a new class LoadStlFactory
Also changed container logic so that if there's only one container specified
in the env spec file you don't need to specify it in SetSample
Centralise code relating to scaling mesh vertices and handling of units
into the LoadShape class and rename it MeshFileIO now that SaveStl is also
descended from this class
Move repeated code to choose Ascii or binary STL reader into a factory class

This creates the framework for a saveRMCProfile algorithm that would be used for saving spectral density data in a format that can be read by RMCProfile.
TODO get propper format of metadata

re: #27774

This commit refactors the the SavePDFGui algorithm to have two seperate functions, one for metadata and one for axis data. This makes any future changes simpler and makes the algorithm easy to duplicate with different metadata for different formats

re: #27774

This commit adds a decstrings of the SavePDFGui.

re: #27774

This PR fixes a bug in SavePDFGui that caused a failure when given histogram data.

re: #27774

It defaults to 500 bins.
This allows event data to be plotted without rebinning first.
This is a change from before when it would all be in one bin.
It does not change the underlying data that remains in events.

Includes unit test, and doc changes.

Newer boost bind seems to be causing
compiler warnings on Windows. It's no
longer required now bind is in the STL.
