d1e6813812 Make side effects for constructor calls use same mechanism as other arguments 
This commit is yet another step to fixing the order of IR side effect instructions. Instead of having a special `StructorCallSideEffects` class for the call itself, I've introduced a `TranslatedStructorCallQualifierSideEffect` class that shares a bunch of common code with `TranslatedArgumentExprSideEffect`, but handles the case where there's no `Expr` for the qualifier of the constructor call. Because this class uses the same ordering as regular argument side effects, these side effects now appear in the correct order, reads before writes.

The test expectations have changed to reflect the new, correct order.

6a47fcaf1f Packaging: Normalize all qlpack.yml files for all languages 
This commit ensures consistency among all of our qlpacks. Here are the
changes:

1. Ensure only modern references are used (codeql-{lang} is converted to
   codeql/{lang}-all or codeql/{lang}-queries where appropriate).
2. Use consistent version numbers. All languages are at 0.0.2 except
   javascript, which is 0.0.3.
3. Convert all `libraryPathDependencies` to `dependencies` with version
   constraints
4. Dependencies from query packs to other packs are always `"*"` since
   these dependencies are always from source and we should get the
   latest.
5. Dependencies from codeql/{lang}-lib to codeql/{lang}-upgrades must
   be strict since there is a tight connection between the libary
   and its relevant upgrades.

There are very few lines of code changed. Almost all changes are moving
files around.
