Fixes #15241

The visitor for RegularElement expects a node_id for the current element in certain cases. However we skip generating one when the element is "static". This causes an error during hydration if the element was incorrectly marked static but the visitor still expects a node_id. See this comment for example cases.

Ideally, the ComponentClientTransformState should have a getNode() method instead of a node property. That would let us bypass the need for checking if the element is static and lazily generate an identifier.

• Prefix your PR title with feat:, fix:, chore:, or docs:.
• This message body should clearly illustrate what problems it solves.
• Ideally, include a test that fails without this PR but passes with it.
• If this PR changes code within packages/svelte/src, add a changeset (npx changeset).

Tests and linting

• Run the tests with pnpm test and lint the project with pnpm lint
