deps: fix ast-value-factory build without shared RO heap

[DaveT1991]

Summary

This fixes a V8 build regression on the v22.x line when Node is configured with --disable-shared-readonly-heap.

Problem

Building Node 22.22.2 without V8_SHARED_RO_HEAP fails in deps/v8/src/ast/ast-value-factory.cc because the code tries to retrieve read-only roots with a shared-RO-heap accessor that is not available in that configuration.

Root cause

The backported V8 change switched AstRawString::AsArrayIndex() to decode cached array indexes using a hash seed from read-only roots, but this call site used the wrong accessor for non-shared-readonly-heap builds.

Fix

• align deps/v8/src/ast/ast-value-factory.cc with the current main branch implementation
• use HashSeed(GetReadOnlyRoots()) at the call site
• update the include list accordingly

Testing

• git diff --check
• manual inspection against the current main branch implementation

Fixes: #62631

It does not do the trick unfortunately
