Change Details

Run mypy, flynt and isort on devtools. Now we use the sames `excludes` as for other linters (flake8, autopep8) Add some type annotations to stay close to the source material, even if `mypy` does not flag any errors when I run it. This is a backport of [[https://github.com/bitcoin/bitcoin/pull/20451 | core#20451]]

Run python linter on contrib directory, excluding only `gitian_updater` which is third-party code. For `mypy` exclude also `macdeploy`, because there are some non-trivial errors that will take more work to be fixed. For `lint-python-encoding`, skip a file that has a `open(filename, self.mode)` false positive. This linter seems a bit too restrictive, but as long as there is only a single false positive it is easiest to just ignore it. This is a backport of core#20451
