7310590f90 Update qldoc FunctionAccess class 
The `FunctionAccess` class doesn't capture accesses of functions in function call expressions.
This update makes that explicit.

19ee64d9ad C++:Lower potentially-dangerous-function precision 
There have been multiple reports of false positives from this query over
time. Now that it has `@security-severity 10.0`, these false positives
look even worse.

The query looks purely for calls to functions with certain names, not
at whether the calls happen in a dangerous context. To justify a higher
precision, the query should only flag calls that happen in a thread or
another non-reentrant context.

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.
