a83bb39d0f Python: Merge SQLAlchemy TextClause injection into py/sql-injection 
As discussed in a meeting today, this will end up presenting an query
suite that's easier to use for customers.

Since https://github.com/github/codeql/pull/6589 has JUST been merged,
if we get this change in fast enough, no end-user will ever have run
`py/sqlalchemy-textclause-injection` as part of LGTM.com or Code
Scanning.

605bd19306 Python: Add CWE-328 to py/weak-sensitive-data-hashing 
Reading over the description at https://cwe.mitre.org/data/definitions/328.html:

> The product uses a hashing algorithm that produces a hash value that can be used to determine the original input, or to find an input that can produce the same hash, more efficiently than brute force techniques.

For the data that does not require computationally expensive hashing, that will be the exactly problems that this query finds 👍 (that is, MD5, SHA1)

9ed61e7663 Python: Port py/polynomial-redos to use proper source/sink customization 
I noticed the configuration/customization files are in the `performance`
folder in JS, but I just kept them in place, since that seems correct to
me.

55d822cc56 Python: Add TypeTrackingNode 
Splits `ModuleVariableNode` away from `LocalSourceNode`, instead
creating a class `TypeTrackingNode` that encapsulates both of these.

This means we no longer have module variable nodes as part of
`LocalSourceNode` (which is good, since they have no "local" aspect to
them), and hence we can have `LocalSourceNode` inherit directly from
`ExprNode` (which makes the API a bit nicer).

Unfortunately these are breaking changes, so we can't actually fulfil
the above two desiderata until the `track` and `backtrack` methods on
`LocalSourceNode` have been fully deprecated. For this reason, we
preserve the present implementation of `LocalSourceNode`, and instead
lay the foundation for switching over in the future, by deprecating
`track` and `backtrack` on `LocalSourceNode`.

c386f4a009 Python: Clean up py/insecure-protocol 
Going all the way to the AST layer seemed excessive to me, so I rewrote
it to do most of the logic at the data-flow layer. In principle this
_could_ result in more names being computed (due to splitting), but in
practice I don't expect this make a big difference.
