refactor: Introduce (empty) SearchInfo class

[claremacrae]

Description

SearchInfo will soon contain selected data passed in from the Query being executed.

This is the Parameter Object pattern: it is a container for information that will be passed down through multiple levels of code, in order to be able to in future pass through more data, without having to update the function signatures of all the layers in between.

Note: Lots of the FilterFunction use don't need the 2nd parameter added, as they only act on the Task.

For now, I've taken the decision to only update the locations that needed to be updated in order to compile, rather than having loads of unused variables.

Motivation and Context

• I found when working with @DanielTMolloy919 on the dependencies code that we needed to pass Task[] down from Query to the filter functions
• Now I want to be able to pass the query file name down as well, in order to allow filter by function to have access to the path of the query block - to provide query.file.path etc in custom filtering and grouping.

Now we pass through a SearchInfo object, rather than keeping on adding more parameters to pass down through all the layers from Query to FilterFunction.

And in future Query can add more data to SearchInfo, and the filters that need that information can use it.

How has this been tested?

• By running tests
• By checking some of the searches in the Tasks-Demo vault.
