Paul Gschwendtner f0c570bd41 feat(dev-infra): pullapprove verify should handle files in conditions (#36661)
Currently, when verifying our pullapprove configuration, we don't
respect modifications to the set of files in a condition.

e.g. It's not possible to do the following:

```
contains_any_globs(files.exclude(...), [
```

This prevents us from having codeowner groups which match a directory,
but want to filter out specific sub directories. For example, `fw-core`
matches all files in the core package. We want to exclude the schematics
from that glob. Usually we do this by another exclude condition.

This has a *significant* downside though. It means that fw-core will not
be requested if a PR changes schematic code, _and_ actual fw-core code.

To support these conditions, the pullapprove verification tool is
refactored, so that it no longer uses Regular expressions for parsing,
but rather evaluates the code through a dynamic function. This is
possible since the conditions are written in simple Python that can
be run in NodeJS too (with small modifications/transformations).
