## Summary
This PR adds some branches so that we infer `Todo` types for attribute
access on instances of `super()` and subtypes of `type[Enum]`. It reduces
false positives in the short term until we implement full support for
these features.
## Test Plan
New mdtests added + mypy_primer report

## Summary
Resolves#15695, rework of #15704.
This change modifies the Mdtests framework so that:
* Paths must now be specified in a separate preceding line:
`````markdown
`a.py`:
```py
x = 1
```
`````
If the path of a file conflicts with its `lang`, an error will be
thrown.
* Configs are no longer accepted. The pattern still take them into
account, however, to avoid "Unterminated code block" errors.
* Unnamed files are now assigned unique, `lang`-respecting paths
automatically.
Additionally, all legacy usages have been updated.
## Test Plan
Unit tests and Markdown tests.
