Setting the `value` attribute of an `<option>` element to a falsy value should result in the empty string. This wasn't happening in all situations previously.
Fixes#11616
* breaking: play transitions on `mount` by default
closes#11280
* only prevent transitions when the component is invalidated

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
closes#12151
The modern AST is an opportunity to tweak things. In the old AST, the start of else (if) branches was the content, now it's the opening bracket, which makes more sense.
Closes#12287

If an even handler is hoisted and said event handler access rest props, we can't be sure whether or not it will access it via `$$props` (optimized) or via `rest()` - therefore we add both as params in this edge case
