Complete extraction of sorted methods used by templates

[jcollins-g]

Fixes #2438.

This finishes an earlier refactor extracting out sort methods and updating the templates to use them. In particular for categories, default to sorting by name unless a categoryOrder is specified in the templates.

Breaking change for templates -- without an update, many templates will lose their sorting behavior.

The following sed scripts can be used to adjust custom templates when run in a directory containing only custom templates. Make backups first. The examples are for MacOS. On Linux, remove the '' after -i.

sed -i '' '
s/documentedCategories}/documentedCategoriesSorted}/g
s/publicLibraries}/publicLibrariesSorted}/g
s/publicClasses}/publicClassesSorted}/g
s/publicConstructors}/publicConstructorsSorted}/g
s/publicExtensions}/publicExtensionsSorted}/g
s/publicConstants}/publicConstantsSorted}/g
s/publicConstantFields}/publicConstantFieldsSorted}/g
s/publicEnums}/publicEnumsSorted}/g
s/publicExceptions}/publicExceptionsSorted}/g
s/publicFunctions}/publicFunctionsSorted}/g
s/publicImplementors}/publicImplementorsSorted}/g
s/publicMixins}/publicMixinsSorted}/g
s/publicProperties}/publicPropertiesSorted}/g
s/publicTypedefs}/publicTypedefsSorted}/g
' *

sed -i '' '
s/hasPublicMixins}/hasPublicMixedInTypes}/g
s/publicMixinsSorted}/publicMixedInTypes}/g
' class.* enum.* mixin.*

This is wild, I love it! Did you benchmark with anything, like Flutter, to see if there was a performance change? I guess I would be surprised if there was anything beyond a tiny change...

[jcollins-g]

@srawlins I did check Flutter, briefly. Without the memoization of sorted results there's a ~3-4% decline in performance. With it, it's within the margin of error on individual runs, but looks to be a very slight improvement if I squint.
