[Wasm-GC] Inline Wasm array operations & allocation
https://bugs.webkit.org/show_bug.cgi?id=245405
Reviewed by Justin Michaud.
Adds JIT inlining for array.get/set operations in both BBQ and B3 tiers.
Allocation inlining is not done yet as it's more complex.
Sets an arbitrary limit on max array length to avoid boundary conditions on the
array index type.
Also simplify some code for struct.get/set as well.
