Purge sort depending functions in favor of parametric functions

[Drodt]

Intended Change

Replace all sort depending functions from KeY and replace them with parametric functions, e.g., int::select -> select<[int]>.

This PR does not affect behavior. In particular, sequences are not (yet) made parametric and the grammar is not really modified.

SortDependingFunction is removed.

Plan

• The grammar cannot be improved, because the sort depending function syntax is also used for fields, especially java.lang.Object::<created>
• Fix all the tests that are sure to break

Type of pull request

• Breaking change (fix or feature that would cause existing functionality to change)
• There are changes to the (Java) code
• There are changes to the taclet rule base

Ensuring quality

• I made sure that introduced/changed code is well documented (javadoc and inline comments).
• I made sure that new/changed end-user features are well documented (https://github.com/KeYProject/key-docs).
• I added new test case(s) for new functionality.
• I have tested the feature as follows: ...
• I have checked that runtime performance has not deteriorated.
• For new Gradle modules: I added the Gradle module to the test matrix in
  .github/workflows/tests.yml

This java.lang.Object::<created> is not a sort-independent function. I am also not aware, way the <..> are back again. Should the new syntax not ``java.lang.Object::#$created`?
