c5360ba46c Python: Fix bad join in method call order computation
This join had badness 1127 on the project FiacreT/M-moire, producing ~31
million tuples in order to end up with only ~27k tuples later in the
pipeline. With the fix, we reduce this by roughly the full 31 million
(the new materialised helper predicate accounting for roughly 130k
tuples on its own).

fa61f6f3df Python: Model @typing.overload in method resolution
Adds `hasOverloadDecorator` as a predicate on functions. It looks for
decorators called `overload` or `something.overload` (usually
`typing.overload` or `t.overload`). These are then filtered out in the
predicates that (approximate) resolving methods according to the MRO.

As the test introduced in the previous commit shows, this removes the
spurious resolutions we had before.

0561a63003 Python: Add test for overloaded __init__ resolution
Adds a test showing that `@typing.overload` stubs are spuriously
resolved as call targets alongside the actual `__init__` implementation.

e8de8433f4 Python: Update all metrics-dependant queries
The ones that no longer require points-to no longer import
`LegacyPointsTo`. The ones that do use the specific
`...MetricsWithPointsTo` classes that are applicable.

20fea3955e Python: Remove points-to from Metrics.qll
Moves the classes/predicates that _actually_ depend on points-to to the
`LegacyPointsTo` module, leaving behind a module that contains all of
the metrics-related stuff (line counts, nesting depth, etc.) that don't
need points-to to be evaluated.

Consequently, `Metrics` is now no longer a private import in
`python.qll`.

987b10ab3e Python: Fix bad join in OutgoingRequestCall
On `keras-team/keras`, this was producing ~200 million intermediate
tuples in order to produce a total of ... 2 tuples.

After the refactor, max intermediate tuple count is ~80k for the
charpred (and 4 for the new helper predicate).

72f5109ec2 Python: Add more overlay[caller] to Flow.qll
These were causing the repo `gufolabs/noc` to spend ~30 seconds
evaluating `ControlFlowNode.strictlyDominates`. Just in case, I added
`overlay[caller] to the other instances of `pragma[inline]` as well.
