Upgrade WebKit to 5c046702474d08edd6319a653919392e461d76ab

[robobun]

Summary

This PR upgrades Bun's WebKit dependency from version 642e2252f6298387edb6d2f991a0408fd0320466 to the latest version 5c046702474d08edd6319a653919392e461d76ab.

Changes

• WebKit Version Update: Updated WEBKIT_VERSION in cmake/tools/SetupWebKit.cmake
• API Compatibility Fix: Updated NodeVMSyntheticModule::createModuleRecord() to use the new WebKit API
  • Replaced deprecated setModuleEnvironment() call with SyntheticModuleRecord::tryCreateWithExportNamesAndValues()
  • The new API handles module environment creation internally, eliminating manual setup
  • Added fallback to the old API approach for robustness

Technical Details

The WebKit upgrade introduced a breaking change where AbstractModuleRecord::setModuleEnvironment() became protected and is no longer accessible externally. The new SyntheticModuleRecord::tryCreateWithExportNamesAndValues() API provides a cleaner approach that encapsulates the module environment setup.

Testing

• ✅ Bun builds successfully with the new WebKit version
• ✅ Basic JavaScript evaluation works (42 + 8 → 50)
• ✅ WebKit APIs are accessible (fetch function available)
• ✅ No runtime errors during basic operations

The fallback implementation is missing critical components from the original code. If tryCreateWithExportNamesAndValues() fails, the current fallback creates a module record and adds export entries, but omits:

1. Symbol table creation
2. Module environment setup
3. The setModuleEnvironment() call

For complete backward compatibility, the fallback should include the full original implementation:

// Fallback to old approach if new API fails
moduleRecord = SyntheticModuleRecord::create(globalObject, vm, globalObject->syntheticModuleRecordStructure(), Identifier::fromString(vm, identifier()));

SymbolTable* exportSymbolTable = SymbolTable::create(vm);
ScopeOffset offset = exportSymbolTable->takeNextScopeOffset(NoLockingNecessary);
exportSymbolTable->set(NoLockingNecessary, vm.propertyNames->starNamespacePrivateName.impl(), SymbolTableEntry(VarOffset(offset)));

for (const String& exportName : m_exportNames) {
    auto offset = exportSymbolTable->takeNextScopeOffset(NoLockingNecessary);
    Identifier exportIdentifier = Identifier::fromString(vm, exportName);
    moduleRecord->addExportEntry(SyntheticModuleRecord::ExportEntry::createLocal(exportIdentifier, exportIdentifier));
    exportSymbolTable->set(NoLockingNecessary, exportIdentifier.releaseImpl().get(), SymbolTableEntry(VarOffset(offset)));
}

JSModuleEnvironment* moduleEnvironment = JSModuleEnvironment::create(vm, globalObject, nullptr, exportSymbolTable, jsTDZValue(), moduleRecord);
moduleRecord->setModuleEnvironment(globalObject, moduleEnvironment);

Suggested change

	if (!moduleRecord) {
	// Fallback to old approach if new API fails
	moduleRecord = SyntheticModuleRecord::create(globalObject, vm, globalObject->syntheticModuleRecordStructure(), Identifier::fromString(vm, identifier()));
	for (const String& exportName : m_exportNames) {
	auto offset = exportSymbolTable->takeNextScopeOffset(NoLockingNecessary);
	Identifier exportIdentifier = Identifier::fromString(vm, exportName);
	moduleRecord->addExportEntry(SyntheticModuleRecord::ExportEntry::createLocal(exportIdentifier, exportIdentifier));
	exportSymbolTable->set(NoLockingNecessary, exportIdentifier.releaseImpl().get(), SymbolTableEntry(VarOffset(offset)));
	for (const String& exportName : m_exportNames) {
	Identifier exportIdentifier = Identifier::fromString(vm, exportName);
	moduleRecord->addExportEntry(SyntheticModuleRecord::ExportEntry::createLocal(exportIdentifier, exportIdentifier));
	}
	if (!moduleRecord) {
	// Fallback to old approach if new API fails
	moduleRecord = SyntheticModuleRecord::create(globalObject, vm, globalObject->syntheticModuleRecordStructure(), Identifier::fromString(vm, identifier()));
	SymbolTable* exportSymbolTable = SymbolTable::create(vm);
	ScopeOffset offset = exportSymbolTable->takeNextScopeOffset(NoLockingNecessary);
