Revisit conditional dependency handling in wheels

[jakirkham]

Currently we have a bunch of logic that uses sed to change out bits of pyproject.toml. Wonder if there is a better option for handling this in pyproject.toml without needing sed

@jakirkham This is largely overlapping with rapidsai/dependency-file-generator#46. There's an open PR for resolving that but it has been stalled. That would solve some of these pieces, specifically the conditionals like [[ $PACKAGE_CUDA_SUFFIX == "-cu12" ]].

However, the alpha_spec piece would not be possible to implement with rapids-dependency-file-generator (at least, it would require a significant expansion of scope). Do you have thoughts on how to accomplish that without sed?

This is being solved with a combination of https://github.com/rapidsai/rapids-build-backend/ and rapidsai/pre-commit-hooks#28.
