fix(core): log error instead of warning for unknown properties and elements (#35798)

Browse Source 
Changes the Ivy unknown element/property messages from being logged with `console.warn` to `console.error`. This should make them a bit more visible without breaking existing apps. Furthermore, a lot of folks filter out warning messages in the dev tools' console, whereas errors are usually still shown.

Fixes #35699.
