Lenny Maiorani f5ced347e6 AK: Prefer using instead of typedef
Problem:
- `typedef` is a keyword which comes from C and carries with it old
  syntax that is hard to read.
- Creating type aliases with the `using` keyword allows for easier
  future maintenance because it supports template syntax.
- There is inconsistent use of `typedef` vs `using`.

Solution:
- Use `clang-tidy`'s checker called `modernize-use-using` to update
  the syntax to use the newer syntax.
- Remove unused functions to make `clang-tidy` happy.
- This results in consistency within the codebase.

Ben Wiederhake cc6d5242d1 AK: Implement and test DistinctNumeric class
This template class allows for easy generation of incompatible numeric types.
This is useful whenever code has to handle heterogenous data (like meters and
seconds) but the underlying data types are compatible (like int and int).

The motivation comes from the Kernel's inconsistent use of pid_t for process and
thread IDs even though the ID spaces are incompatible, and translating forth/back
is nontrivial.

Other uses could be units (as described above), or incompatible index systems.
A popular use in real life is image manipulation, when there are multiple
coordinate systems.
