Error when creating an accessor for an prop

[Thiagolino8]

Describe the bug

When creating an accessor to an prop without using svelte:options, If you create an accessor for a binded prop using export its value becomes an internal function, if you try to export a prop that is used as an object the compiler tries to export using a variable that is never declared

What's the use case? What's the Svelte 4 equivalent? I think exporting things from $props() should be a compiler error.

[Thiagolino8]

The use would be to create individual prop accessors instead of all at once using the accessors option

[dummdidumm]

It would be confusing to explain why you can export $state like that from a component and it behaves differently compared to an export from a module. The "workaround" is to just export a function which returns the current value, which also better conveis the "this can change" notion -> this code should be a compiler error.

note that we reverted this change in #10523, this will now work
