Update Package.swift and .spi.yml to make them match

Package.swift and `.spi.yml` have drifted apart and didn’t actually match anymore. The targets declared in `.spi.yml` should match the libraries declared in the package manifest. To fix this, update `.spi.yml` and also declare `SwiftBasicFormat` as a library in `Package.swift`. BasicFormat is being used in sufficently many places by now that we can’t really consider it an implementation detail of SwiftSyntax anymore.
