Aleksey Kladov dbb702cfc1 internal: remove accidental code re-use
FragmentKind played two roles:

* entry point to the parser
* syntactic category of a macro call

These are different use-cases, and warrant different types. For example,
macro can't expand to visibility, but we have such fragment today.

This PR introduces `ExpandsTo` enum to separate this two use-cases.

I suspect we might further split `FragmentKind` into `$x:specifier` enum
specific to MBE, and a general parser entry point, but that's for
another PR!
