feat(webpack,rspack): add typeCheckOptions, runtimeDependencies, and cache options

[davidantoon]

Current Behavior

• The skipTypeChecking option is a simple boolean that only allows enabling/disabling type checking
• Rspack executor is missing the runtimeDependencies option that webpack has
• The cache configuration is hardcoded and cannot be overridden by users

Expected Behavior

• New typeCheckOptions option allows configuring type checking with { async: true } to run type checking in a separate process without blocking the build
• The deprecated skipTypeChecking option is maintained for backward compatibility
• Rspack now supports runtimeDependencies option for adding runtime dependencies to generated package.json (useful for Docker installs)
• New cache option allows users to override webpack/rspack caching behavior while maintaining backward-compatible defaults

Changes Made

typeCheckOptions (webpack & rspack)

• Added TypeCheckOptions interface with async property
• Added typeCheckOptions option to plugin options interfaces
• Updated apply-base-config.ts to normalize typeCheckOptions from deprecated skipTypeChecking for backward compatibility
• Added schema definitions to schema.json and schema.d.ts

runtimeDependencies (webpack & rspack)

• Added runtimeDependencies option to NxAppRspackPluginOptions
• Updated GeneratePackageJsonPlugin to resolve and include runtime dependencies
• Added schema definitions to schema.json and schema.d.ts

cache (webpack & rspack)

• Added cache option to plugin options interfaces
• Updated apply-base-config.ts to check 'cache' in options before applying defaults
• Allows explicit cache: undefined to force cache to be disabled
• Maintains backward-compatible defaults:
  • Webpack: { type: 'memory' } for Node targets in watch mode
  • Rspack: true for Node targets in watch mode, true in dependent config
