Merge the lit and unit test suite.

Rename `check-llvm-dialects` => `check-llvm-dialects-lit`
Add a new custom target `check-llvm-dialects` that runs both
`check-llvm-dialects-lit` and `check-llvm-dialects-units`.

Run the combined test suite on CI.

While we only use the units test suite for `OpMap` and `OpSet` right
now, it makes sense to have them executed both under a common name.
