  [WASM-Function-References] Extend tables with initializer expressions
https://bugs.webkit.org/show_bug.cgi?id=251123

Reviewed by Justin Michaud.

Add support for tables with initializer expressions. This entails extending
TableInformation with initialization information, just as there is for globals.
The same fast paths for initializer expressions are used for tables, except
restricted to the ones that make sense for reference types.
