fix: Add some missing TS exports

[devongovett]

Adds some types that were not exported before but people were using due to d.ts files allowing non-exported types to be imported: microsoft/TypeScript#38592.

Also fixes @react-spectrum/s2/style/tokens.d.ts referring to @adobe/spectrum-tokens which is a dev dependency by inlining the keys in the built types.
