It's been a couple of times mypy breaks the pipeline by releasing new
versions that are more strict or start checking things it used to
silently ignored.

In order to avoid this happening in the future (and putting us back in
control), this pins the mypy version to the exact release (the last
we successfully built with, in this case), and moves everything we
install though pip install into requirements-dev.txt files so that
@dependabot can help us stay up-to-date going forward.

Fixes #2464

Removed those limits because they're no longer necessary (they're mostly useful when you "just enabled" dependant on a codebase with a lot of outdated dependencies). This would improve our ability to remain up-to-date...

Looks like this PR includes more then just pinning mypy, but ok...

Updated the type annotations of the jsii runtime for Python so that the
decorators carry appropriate type signatures. Additionally, enhanced
the code generation for Python so that mypy errors that are difficult or
impossible to address are ignored by the tool without requiring specific
user configuration.

Relates to #2464, #2476
