feat(sca): add types for new potential lockfile/manifest types (#315)

This PR adds types for the Python UV & Conan C++ manifests and
lockfiles.

- [x] I ran `make setup && make` to update the generated code after
editing a `.atd` file (TODO: have a CI check)
- [x] I made sure we're still backward compatible with old versions of
the CLI.
For example, the Semgrep backend need to still be able to *consume* data
generated
	  by Semgrep 1.17.0.
