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.

/**
|
|
* Provides classes for performing local (intra-procedural) and
|
|
* global (inter-procedural) taint-tracking analyses.
|
|
*
|
|
* We define _taint propagation_ informally to mean that a substantial part of
|
|
* the information from the source is preserved at the sink. For example, taint
|
|
* propagates from `x` to `x + 100`, but it does not propagate from `x` to `x >
|
|
* 100` since we consider a single bit of information to be too little.
|
|
*
|
|
* To use global (interprocedural) taint tracking, extend the class
|
|
* `TaintTracking::Configuration` as documented on that class. To use local
|
|
* (intraprocedural) taint tracking between expressions, call
|
|
* `TaintTracking::localExprTaint`. For more general cases of local taint
|
|
* tracking, call `TaintTracking::localTaint` or
|
|
* `TaintTracking::localTaintStep` with arguments of type `DataFlow::Node`.
