feat(rattler): port conda build recipe to rattler build (rapidsai#121)

Port all condabuild recipes over to use `rattler-build` instead.

Contributes to rapidsai/build-planning#47
Contributes to rapidsai/build-planning#84

- To satisfy `rattler-build`, this changes all the licenses in the `pyproject.toml` files to the SPDX-compliant `Apache-2.0` instead of `Apache 2.0`
