Update expected test results after frontend update
Update MISRA queries and tests after merging location tables
C++: accept new test results after QL changes
Observe that `sizeof(...)` might not occur as a dataflow node if it has a parent node with a concrete value. That value will be a dataflow node instead. Hence, the query has be changed to check for expressions where `sizeof(...)` is a child of an expression with a concrete value.
Note that we now properly report the offending cast instead of the expression that is being cast.
As it is the dataflow used by `asctime` that is relevant, and not the pointer, use the indirect expression.
Convert a number of queries to use the new dataflow library
Update expected test results for MSC33-C
These use the new dataflow library
Since the new dataflow library uses use-use dataflow and not def-use dataflow, we now need to check for definitions. Note that these queries can probably be improved by using a dataflow configuration - possibly limited to the local context of a function by including `DataFlow::FeatureEqualSourceSinkCallContext`

Description
This pull request upgrades CodeQL dependencies, updates dataflow and concurrency imports to use newer modules, and refines several rule implementations for improved accuracy and maintainability. The changes ensure compatibility with the latest CodeQL libraries and enhance the precision of certain queries.
Dependency and Import Upgrades:
codeql/cpp-allto version 6.0.0 and updated several other CodeQL dependencies to their latest versions in bothqlpack.ymlandcodeql-pack.lock.yml. Also addedcodeql/controlflowas a new dependency.

Release change checklist
A change note (development_handbook.md#change-notes) is required for any pull request which modifies:
If you are only adding new rule queries, a change note is not required.
Author: Is a change note required?
🚨🚨🚨
Reviewer: Confirm that format of shared queries (not the .qll file, the
.ql file that imports it) is valid by running them within VS Code.
Reviewer: Confirm that either a change note is not required or the change note is required and has been added.
Query development review checklist
For PRs that add new queries or modify existing queries, the following checklist should be completed by both the author and reviewer:
Author
As a rule of thumb, predicates specific to the query should take no more than 1 minute, and for simple queries be under 10 seconds. If this is not the case, this should be highlighted and agreed in the code review process.
Reviewer
