FAIRmat 2024: additional base classes in NXinstrument

[lukaspie]

This PR adds four unnamed base classes to NXinstrument.

• NXactuator: see description/discussion in Fairmat 2024: actuators and sensors in NXenvironment #1414
• NXfabrication: see description/discussion in Fairmat 2024: actuators and sensors in NXenvironment #1414
• NXhistory: this is a new base class that is meant to describe the history of any physical object (in this case, the instrument history). NXhistory is meant to contain many instances of the new base class NXactivity, which describes any physical activity that was performed on the physical entity prior or during the experiment. Note this is intentionally different than NXprocess, which describes processing of the data.
• NXresolution: This is meant to describe the resolution of a measureable physical quantity. Here, we are describing many different ways of a) how such a resolution can be described, and b) how such a resolution can be obtained. For b), we are also moving the base class NXcalibration (a subclass of NXprocess) from contributed to base_classes and slightly expand its former definition .

In addition, NXnote is expanded to contain more information about a given resource (like the URI of the resource, the checksum of a file, etc.).

@phyy-nx I also made one more change in that I changed the links in the NXcalibration docs to point correctly to the concepts in NXdata:

Ready for final review and merge.
