Remove Numeric Fallback of Symbols (#23348)

This was already defeating the XSS issue that Symbols was meant to protect
against. So you were already supposed to use a polyfill for security.

We rely on real Symbol.for in Flight for Server Components so those require
real symbols anyway.

We also don't really support IE without additional polyfills anyway.
