fix: resolve the fallback of an each block in the enclosing scope (#18803 )

In `phases/scope.js`, `EachBlock` visits `node.fallback` with the
block's own scope, so `{:else}` resolves the loop's name to the each
context. With `let item = $state('outer')` outside and `{#each items as
item}…{:else}<button onclick={() => (item = 'changed')}>` the compiler
reports "Cannot reassign or bind to each block argument" for a variable
that is not the block's argument.

The fallback renders when there is nothing to iterate, so it is visited
in the enclosing scope, as an await block's `pending` is.
