ghc-internal: move all Data instances to Data.Data

Most instances of Data are defined in GHC.Internal.Data.Data.
Let's move all remaining instance there.

This moves other modules down in the dependency hierarchy allowing for
more parallelism, and it decreases the likelihood that we would need to
load this heavy .hi file if we don't actually need it.

Resolves #26830

Metric Decrease:
    T12227
    T16875
