As a byproduct of #12239 some types were changed from being directly exported to indirectly exported. TypeScript is bad at following these types while generating d.ts files, so we can't do that. A check at the end of the types generation was added to prevent regressions in the future. Fixes#13128
Also removes the old types from `svelte/reactivity` which are deprecated for a while now.
Uses new dts-buddy capabilities and the corresponding tsconfig option to strip away types/properties (and their dependencies) that are marked with `@internal`
Also hides the legacy AST types from the output
To not clutter the exports, the AST types are moved into a namespace named AST

language tools has to type its own shape for backwards compatibility, and it currently doesn't include the `$on` and `$set` methods, which means without widening the type as done here you would get a "this shape is not accepted" type error when passing it to `ComponentProps`

This aligns warning and error objects to contain the same properties and have their toString methods return the same shape. It's implemented by warnings becoming class objects, too, and sharing the same base class with errors. It also adds back the `frame` property that got lost in the Svelte 4->5 transition. The only difference to Svelte 4 now is a slightly adjusted toString property (which is consistent between warnings and errors now) and a `position` property that contains a tuple of start/end offsets instead of a `pos` property only containing the start offset

#12202 revealed that TypeScript has a harder time tracing imports when they are indirectly exposed, e.g. `function foo(): void; ... export { foo }` instead of `export function foo(): void;`, which can lead to bugs down the line (such as in that issue). A new `dts-buddy` version fixes this, which in turn fixes#12202
This also adjustes the `Snippet` type and turns it into an interface, which makes for better intellisense: The type will be unpacked in less situations, resulting a more readable and named type.
