Kefu Chai df63e2ba27 types: move types.{cc,hh} into types
they are part of the CQL type system, and are "closer" to types.
let's move them into "types" directory.

the building systems are updated accordingly.

the source files referencing `types.hh` were updated using following
command:

```
find . -name "*.{cc,hh}" -exec sed -i 's/\"types.hh\"/\"types\/types.hh\"/' {} +
```

the source files under sstables include "types.hh", which is
indeed the one located under "sstables", so include "sstables/types.hh"
instea, so it's more explicit.

Closes #12926
