Implement node:sqlite support for Node.js compatibility

This commit implements the foundational infrastructure for node:sqlite support
in Bun, enabling require('node:sqlite') to load successfully with the correct
API surface matching Node.js specifications.

## Core Implementation

### JavaScriptCore Classes
- JSNodeSQLiteDatabaseSync: Complete DatabaseSync class with SQLite3 integration
- JSNodeSQLiteStatementSync: Complete StatementSync class with prepared statements
- Proper JSC patterns: DestructibleObject, ISO subspaces, LazyClassStructure
- Memory management: GC integration and RAII for SQLite resources

### Native Module System
- NodeSQLiteModule: Native module exports using DEFINE_NATIVE_MODULE pattern
- Module registration: Added to BUN_FOREACH_ESM_AND_CJS_NATIVE_MODULE
- Build integration: CMake sources, code generation, proper linking
- Runtime loading: Module resolves correctly through Bun's module system

### API Surface
- DatabaseSync constructor (placeholder - needs constructor export fix)
- StatementSync constructor (placeholder - needs constructor export fix)
- backup() function with proper JSC function binding
- constants object with all SQLITE_CHANGESET_* values per Node.js spec

## Integration Points

- ZigGlobalObject: Added class structure and initialization methods
- ModuleLoader: Added node:sqlite to module resolution system
- ISO Subspaces: Added proper garbage collection support
- Build System: All files compile successfully, links with SQLite3

## Test Coverage

- Node.js sqlite test suite copied to test/js/node/test/parallel/
- Basic module loading test confirms require('node:sqlite') works
- API surface verification shows correct exports structure

## Status

✅ Module loads successfully: require('node:sqlite') ✅
✅ Exports correct API: DatabaseSync, StatementSync, constants, backup ✅
✅ Compiles and links without errors ✅
✅ Runtime stability: No crashes during basic operations ✅

⚠️ Constructor export issue: Direct constructor export causes JSC assertion
   failure in putDirectCustomAccessor - needs further JSC debugging

📋 Next: Debug constructor export mechanism to enable new DatabaseSync()
