Rework Template Haskell's handling of strictness
Currently, Template Haskell's treatment of strictness is not enough to
cover all possible combinations of unpackedness and strictness. In
addition, it isn't equipped to deal with new features (such as
`-XStrictData`) which can change a datatype's fields' strictness during
compilation.
To address this, I replaced TH's `Strict` datatype with
`SourceUnpackedness` and `SourceStrictness` (which give the programmer a
more complete toolkit to configure a datatype field's strictness than
just `IsStrict`, `IsLazy`, and `Unpack`). I also added the ability to
reify a constructor fields' strictness post-compilation through the
`reifyConStrictness` function.
Fixes #10697.
