This is step two of fixing the ordering of call side effects. This commit refactors the existing `TranslatedSideEffect` class into an abstract `TranslatedSideEffect` class, which contains functionality common to all kinds of side effect, and a concrete `TranslatedArgumentSideEffect` class, which is the implementation of argument side effects. A future commit will add additional concrete classes for conservative call side effects and allocation side effects.
This change has zero diffs to the generated IR.
This is the first step to fixing the order of side effects on call instructions. The goal is to move all side effects (argument side effects, allocation side effects, and conservative call side effects) to be treated as elements in a single sequence of side effects, which will then be handled in a single place similar to how we already handle argument side effects.
This PR separates the core cpp packs into `codeql/cpp-queries` and
`codeql/cpp-all`.
There are very few lines of code changed. Almost all changes are moving
files around.
